Suggested April 2024 How To Undervolt Your Cpu With Throttlestop In Windows
The more strenuous the tasks you carry out on your PC, the more your CPU (processor) will heat up, and the more vital it is to reduce CPU temperature. This becomes particularly noticeable during gaming or heavyweight video-editing, but your CPU may be prone to overheating anyway if it’s poorly ventilated, or the thermal paste on the CPU has worn out. Luckily, there’s a borderline-miraculous tool that can reduce high temperatures and reduce power usage by a process called “undervolting.”
It’s called Throttlestop, and this article shows you how to use it to undervolt your CPU.
Note: if you’re unsure about whether your CPU temperatures are too hot, read our guide on how to monitor your PC temperature in Windows. Certain laptops are also locked off from undervolting, which you can check by looking for a “Locked” sign in the Throttlestop FIVR menu.What Is Undervolting?
Before pushing on, it’s worth knowing what undervolting is, as it’s a pretty serious process. While undervolting doesn’t damage your CPU, overdoing it can make your system unstable (though it’s easy to reverse). Overvolting, on the other hand, can damage your CPU if abused, but used carefully, can allow you to overclock your CPU to higher speeds. (We won’t be covering that today.)
Undervolting, simply put, reduces the amount of power/voltage being directed to your CPU. The more power sent, the hotter it gets. The less power, the cooler it gets. Simple. Another perk of undervolting for laptop users is that it extends battery life.
Best of all, undervolting your CPU doesn’t noticeably affect performance, even during high-intensity activities like gaming. It really is as good as it sounds!Throttlestop Features
Throttlestop is a tool with many purposes. Its very name refers to its use in overriding throttling systems in your CPU to increase performance, but we kind of do the opposite here.
First, download and install Throttlestop, then open it.
Let’s take a look at the checkboxes on the main Throttlestop screen.
We’re only going through the ones that are relevant to modern CPUs, as several of those boxes relate to features for much older PCs. The following are the features you should look for:
Disable Turbo: this setting will ensure that none of the cores on your CPU run faster than their base clock speed. If you have a base clock speed of 2.6GHz that’s capable of Turboing up to 3GHz, checking this box will make sure it stays in the 2.6GHz region instead of boosting.
BD Prochot: a safety feature that seriously throttles your CPU when things get too hot inside your laptop. Generally, throttling will kick in when your CPU reaches 100C, but with this box ticked, the CPU will throttle even when your GPU gets too toasty. It’s a handy safety measure that’s worth having turned on for those rare extreme cases.
Speed Shift: on more recent CPUs (2024 onward), Intel released this feature, which helps the CPU respond faster to changes in the software-set clock speed. If this option appears in Throttlestop for you, then you should switch it on.
SpeedStep: if your CPU is older than the Intel Skylake generation (2024), then Speedstep does the same job as Speed Shift. By all means, switch this on if you have an older CPU.
C1E: switching this on will help save power when you’re running low on battery, as Throttlestop will switch off your cores automatically, based on how much strain they’re under. You don’t need to have this on when plugged into the mains.Undervolt Your CPU Using Throttlestop
Next up is the four select-circles at the top left. These let you switch between different profiles, each of which can have its own undervolt settings. To explain how things work, we’ll setup a gaming profile.
Switch the profile using the radio buttons to “Gaming” or any profile you want. For instance, if you set it to “Battery,” you can optimize your CPU for battery savings.
Tick the “Unlock Adjustable Voltage” box in the new window.
Decrease the “Offset Voltage” slider, which is the undervolting part. It’s recommend to decrease this to “-100mV” to start.
Different CPUs can handle different levels of undervoltage, so you’ll need to experiment a bit to find out the limits for your CPU.
If you want to avoid having to open Throttlestop manually each time you want to undervolt, you can set it to open on Windows startup. Refer to our guide on how to use the Windows Task Scheduler for more info.
Using this method, I reduced my CPU gaming temperature from nearly 90°C down to a much less alarming 70ºC to 75°C. This is just about as much effect as you can have on your CPU temperature from within Windows.
If you’re still having trouble, though, you may want to think about opening your PC to blow away the dust.Frequently Asked Questions How can I learn more about how to use Throttlestop?
If you want to do more than just undervolt your CPU and reduce CPU temperature, check out the guide that comes with your Throttlestop download. This provides tutorials and tips in the form of a YouTube video. If you don’t have the guide, check out the official video here.Are there other ways to reduce CPU temperature?
If Throttlestop isn’t working for you or you can’t use it, you can reduce your CPU temperature by decreasing how much you do at once. You may also want to consider installing a CPU cooler. There are different varieties to best meet your needs. You may also want to try these troubleshooting steps to see if something else is wrong.What if Unlock Adjustable Voltage is grayed out?
This means your computer doesn’t support undervolting using Throttlestop. You’ll need to find another way to cool your CPU.
If you have an Intel processor on Windows, you may be able to use the Intel Extreme Tuning Utility instead.Do I need to worry about undervolting my AMD CPU?
Most modern AMD CPUs have a different architecture to run at lower temperatures, especially when compared to Intel processors. This is especially true with AMD’s Ryzen 5000 series. However, if you do notice higher temps, you can still try undervolting. Throttlestop may not work on AMD Ryzen CPUs, though. If it doesn’t, try AMD Ryzen Master instead.Why doesn’t Throttlestop work on Windows 11?
This isn’t an issue for all Windows 11 users, but many users switching from Windows 10 to Windows 11 have reported that Throttlestop is no longer working for them. The common theme appears to be virtualization, especially issues with WSL 2 (Windows Subsytem for Linux).
You can try to disable virtualization via your BIOS. Some systems don’t have an option to disable it. However, if you really need to undervolt your CPU on Windows 11, it’s worth trying to disable virtualization in your BIOS to see if this is the problem.

How to Lower High CPU Temperature in Windows 10 & 11?
Except for a few moments following an update, it is usually not Windows that causes excessive CPU consumption.
If you’re getting warnings about high CPU temperatures, it might be due to a conflicting application you’ve installed that peaks at high CPU temperature.
Incompatibility between your PC’s drivers and other components might be the root cause of these events.
Using this guide, you may perform several troubleshooting scans to identify which area of your PC is generating a high CPU temperature.
INSTALL BY CLICKING THE DOWNLOAD FILE
We suggest Fortect to handle a variety of CPU-related issues:
This software will optimize your PC for maximum speed, fix common computer errors, and safeguard you against data loss, CPU issues, and hardware failure. This is how you can solve PC issues and remove corrupt files in 3 easy steps:
Download and install Fortect.

A high temperature isn’t a good sign because it can lead to lower performance or in some cases permanent damage to your computer, so if you’re a Windows 10 user, and you’re experiencing high CPU temperature, you might want to learn more about it.
Users have reported lower performance which includes stuttering while watching multimedia, or while playing video games, and some users have even reported unexpected shutdowns. The unexpected shutdown isn’t a good sign because it means that your CPU temperature is too high and the computer shuts itself down in order to prevent any physical damage.
On top of that, here are some more similar issues that are connected to high CPU temperatures in Windows 10:
Windows 10 overheating shutdown – If the CPU temperature gets too high, your computer will automatically shut down to prevent any hardware damage.
Windows 10 Anniversary Update overheating – Numerous users reported back in the day that high CPU temperatures occurred after installing the Anniversary Update.
Windows 10 Creators Update overheating – Unfortunately, it was the same for the Creators Update.
Windows 10 overheating laptop – Laptops also tend to overheat. Some of the ‘hottest’ brands are HP, Asus, and Dell.What to do if the CPU temperature gets high 1. Use the Power Troubleshooter and check for issues
The first thing we’re going to try is also the simplest one. We’ll just let the troubleshooter do the work for us. Here’s how to run the Power Troubleshooter in Windows 10:2. Perform a Clean Boot
If you’re not familiar, Clean Boot lets you disable all the apps that might be starting with your Windows 10. By default, Windows 10 starts only the core applications that it needs, but as you install more software, that software sometimes automatically starts with your Windows, and sometimes it can cause high CPU usage as well as high temperature. So in order to disable all the non-core apps and processes that might be starting with Windows 10, you need to do the following:3. Clean your CPU fan or change it
Sometimes CPU temperature issues are caused by dust that gets stuck in the fan, so you might need to clean it, or in some other cases, you might need to replace your CPU fan completely. If you don’t know how to do this, please contact an expert to do it for you.4. Your hardware might not be compatible with Windows 10
Windows 10 is still a new operating system and there could be certain issues with some hardware. Your motherboard or CPU might not work well together in Windows 10 although they have worked fine in the previous versions of Windows. Changing your expensive hardware isn’t the best option, and we hope that Microsoft will release an update that will fix the hardware incompatibility issues in near future.
High CPU temperature on Windows 10, or any other Windows is a major concern, it can lead to unexpected shutdowns and other issues, and it can even cause permanent damage to your computer in some cases, so treat it with caution.5. Run the SFC scan
The SFC scan is another troubleshooting tool we’re going to try. You can use this tool to resolve various issues inside the system. And by resolving system issues, hopefully, you’ll be able to cool down your computer, as well.
Here’s how to run the SFC scan in Windows 10:6. Run DISM
And the last built-in troubleshooting tool we’re going to use is the Deployment Image Servicing and Management (DISM). As its name says, this tool freshly deploys the system image and fixes some potential problems along the way. Hopefully, it’ll relieve us of the high CPU temperature.
Open the Command Prompt as shown above.
Enter the following command and press Enter:
/Online /Cleanup-image /Restorehealth
Wait for the process to finish.
Restart your computer.
In case the DISM can’t obtain files online, try using your installation USB or DVD. Insert media and type following command:
/Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess
Make sure to replace ”C:RepairSourceWindows” path of your DVD or USB.
Follow further on-screen instructions.7. Update BIOS
Keeping your BIOS up to date is essential for your computer’s functioning. If your BIOS version is outdated, it may interfere with some newer hardware drivers and cause unwanted issues, including CPU overheats.
Unfortunately, updating BIOS is a risky and complicated procedure. You can read more about it in our How to flash BIOS article. But remember to act with caution, or ask a professional to update your BIOS. If you make a wrong step, you may badly damage your system.8. Turn off the integrated GPU
Chances are your CPU features an integrated GPU. Because most of the newer CPUs do. And if you’re using a dedicated GPU, you don’t really need the integrated one. On top of that, having both GPUs turned on may rise the CPU temperature. So, your best bet is to simply disable the integrated GPU, since you’re not using it.
Unfortunately, that’s not so simple and usually depends on your motherboard and configuration. That’s why we can’t post the exact instructions on how to disable your integrated GPU here. So, find out your motherboard and CPU model, and search the internet for the instructions on how to disable your integrated CPU.9. Check for memory leaks
Memory leaks are a major foe of your computer’s performance. A memory leak caused by an app or program will drastically slow down your computer. However, it will also put extra pressure on your CPU, therefore causing it to overheat. If you have no idea what memory leaks are, we have a lengthy explainer/guide on how what are memory leaks and how to fix them. So, make sure to check it out. Maybe there’s a memory leak in your system, and you don’t even know it.10. Reinstall Windows
If none of the previous solutions worked, you probably should reinstall your system as a last resort. Maybe there’s something else inside that just keeps raising the CPU temperature. So, the fresh installation might just be the best solution.
There are multiple ways to factory reset Windows 10, and if you don’t know any, check out our detailed guide for additional info and tips.

Windows Widgets High CPU Usage: How to Fix it on Windows 11
The most common reason for high CPU usage is that your computer is running too many applications at once.
Windows 11 is a feature-packed OS and without enough memory, the widgets could end up consuming too much CPU.
A simple reboot of your system can get rid of temporary files and solve the high CPU usage problem.
If you notice that one particular app is using an unusually large amount of resources on your PC, then you should consider closing it or uninstalling it to make your PC run more smoothly again.
Windows 11 has a built-in widget platform and can contribute to high CPU usage. These widgets can be used to display the weather forecasts, sports scores, and clock.
Whereas they may be useful to some extent, some users complained that Windows 11 Widgets are using too much CPU. This widget issue is most common on Windows 11 devices, but older versions of Windows can also experience this problem.
The widgets are a useful feature that provides you with information at a glance. But, sometimes, when the Widget panel is open, it starts consuming CPU or memory and the system performance drops down.
The CPU is the brain of your computer. It performs all the calculations and processes that your machine needs to function, so if it’s running unusually slow, you may want to investigate the issue.
If a widget is using up most of your computer’s resources (CPU, memory, disk space, etc.) then you should turn it off because that means it is using up all of the resources that could be used by other processes, thus slowing down your computer.
There are several causes of high CPU usage. It may be that you have installed too many programs on your computer and they are taking up too much space. The best solution to this problem is to uninstall some of those programs from your computer.
It is also possible that there has been an infection on your system that has caused the files to become infected with viruses or spyware. This will cause the computer to run more slowly and use more resources than normalDoes Windows 11 use more CPU than Windows 10?
Windows 11 is more demanding than its older siblings. This is quite evident in the minimum system requirements.
The OS has also been designed with security in mind. It includes built-in antivirus and firewall protection, as well as a host of other security features.
Another reason why Windows 11 uses more CPU is that it has several features that were not possible with Windows 10. The inclusion of new application programs has been designed for use only with Windows 11.
With the widgets on Windows 11, it is likely to take up more CPU than Windows 10. If you want to stop your CPU from using too much energy, you will need to turn off some of the features that cause it to do so.
For example, you can tweak the Power Management settings which allow the computer to turn off when it’s not in use.
Be sure to check out the differences and similarities between Windows 10 and Windows 11 to better understand the two operating systems..What can I do to fix Windows 11 widgets high CPU usage? 1. Disable widgets from Task Manager
The tool also works in the background and keeps your drivers always up-to-date. It automatically scans your PC for devices and checks if there are new versions of their drivers available.3. Run a system scan 4. Run DISM command 5. Run SFC command How can I check for CPU usage in Windows 11?
At some point, the performance of your PC will prompt you to check what is consuming too much CPU so you can disable it.
There are many reasons why Windows 11 runs slow, and there are many possible solutions. For example, some programs may require more system resources than others. It is possible that your computer might be running slow because it has an outdated driver or software.
To get to the root of the problem, you will need to check the CPU usage. Here’s how to check your CPU usage in Windows 11:Do widgets drain battery?
Apart from CPU consumption, another common question that comes up often is whether widgets drain batteries.
Most obviously, if you run more software, the more work your computer will do, and so the faster its battery will drain.
If you are using a widget, it’s a good bet that the app that created it is running in the background, occasionally waking up to update itself.
Depending on what the widget does, and how often it does it, this can use up more battery than you want. If the widget is a clock, for example, the app might be waking up every couple of minutes to update its display.
While it isn’t necessary to delete all of your widgets, it’s best to keep only those that you absolutely need. If you have widgets for weather apps or social media apps that you don’t use very often, consider deleting them from your home screens.
You can also apply some of our recommended solutions to make your Windows 11 faster and more responsive.
We also have an excellent guide on software you can use to fix high CPU usage and save yourself some of these troubles.
If your widgets were consuming a considerable amount of CPU, we hope this article has offered efficient solutions and your PC’s performance has improved.

Few features in Windows have as colored a history as AutoPlay. In its early days, the setting was infamous for passing viruses from errant USB drives to PCs. In more recent versions of Windows, AutoPlay is off by default to prevent malicious files from automatically executing on a PC.
AutoPlay is handy because it tells Windows to automatically carry out a specific action when you plug in some kind of removable media such as an SD card, a USB drive, or an external CD player. AutoPlay can be set to automatically import photos or videos, play any media, open File Explorer, or do nothing at all.
Even in the age of Windows 10, the best practice for AutoPlay is to leave it off or to have it ask you what to do every time you insert a device. If that doesn’t work for you, the next most benign step you can take is to set AutoPlay to open File Explorer. That way you can still see what’s on the USB stick, which is probably an action you would’ve taken anyway.
Here’s how it works in Windows 10. This example uses the Anniversary Update, but previous iterations offer similar settings.
This section may change depending on your machine’s configuration. On my laptop I have options to decide what to do with a USB removable drive (flash drive, external hard drive, etc.) and a memory card.
In our example, we’re setting each option to open the files in File Explorer for immediate viewing. To do that, select each drop-down menu and choose Open folder to view files (File Explorer). If you’d rather open File Explorer yourself, choose the Take no action option.
AutoPlay settings in the Control Panel in Windows 10 (Anniversary Update).
Next, set the View by option in the control panel to Large icons. Then select AutoPlay at the top of the window. From here you can tell Windows to do specific things based on the type of media and the files it has.
For example, you can tell a removable drive to automatically import photos but take no action for videos. There are numerous options you can set using Control Panel, but again it’s important to understand that using AutoPlay at all can be an easy way to end up with an infected PC.
Of course, there’s more to USB security than just disabling AutoPlay. Check out Stack Exchange for a short discussion about threats from external media beyond using AutoPlay. The most important thing to know is that you should never plug a USB device into your computer if you don’t trust it or don’t know where it came from.
Even if you do trust a USB device (such as one that you own), you still may not be able to treat it as safe, depending on where it’s been. If you used a personal USB drive at work and then brought it home to insert in your personal machine, watch out. You never know what kinds of horrible things are lurking in corporate networks, your local internet cafe, or even your friend’s house.
Are you losing GBs of storage space because you forget to clear your trash? With AutoTrash, you can get Ubuntu to empty trash automatically on its own, based on the conditions you specify.Installation of AutoTrash
You won’t find AutoTrash in many distributions’ repositories anymore. For most users, the easiest way to install it is through an unofficial snap version, available at the snap store.
If using Ubuntu, which in its latest versions already supports snaps by default, you can find the program in the software center by searching for “autotrash.”
If the program isn’t available through your distribution’s repositories but you also have a distaste for snaps, there is a solution. Since it’s a Python script, you can use pip to install autotrash with:pip
When you install it like that, for ease of use, make sure to include its location in your PATH variable.Set an alias
If you installed AutoTrash through the simpler route of snap, you can try it by typing autotrash-unofficial in a terminal. Alternatively, you can set up an alias for easier access.
If you would prefer to type autotrash instead of autotrash-unofficial to run the tool, type the following in the terminal:
aliasautotrash-unofficial autotrash Clean your Trash
AutoTrash comes with a list of parameters that allow you to customize how it will clear your trash.
Using -d, you can define a date threshold. Everything moved to the trash within the specified number of days will remain intact; AutoTrash will wipe out everything older. For example, to eliminate all files older than 10 days, use:autotrash
If you have ample free space, there is no point in trying to free up even more by removing older files. Instead of checking it yourself, though, you can specify a free space threshold with --max-free. The values are in megabytes.
If you want AutoTrash to exterminate everything older than ten days only if your free space has dived under 4 GB, you would use:autotrash
Since 1 GB = 1024 MBs, the above number translates to 4 GB (4 x 1024).
You can have AutoTrash ensure that you always have at least 512 megabytes of free space available with:autotrash
You can change 512 to whichever value you prefer.
It’s best to always make sure the results of any action will be what you originally intended. You can have AutoTrash perform a test run that makes no actual changes to your data, using the --dry-run switch. This doesn’t come with any extra values. Include it as is at the end of your command to check its outcome. Thus, with this addition, the previous example would look like:autotrash
Having to run AutoTrash to purge the contents of your trash manually is far from optimal. Thankfully, it’s easy to have it run automatically. You can set up a cron job for that, but we think the following approach is even more straightforward.
Search for “startup” among your applications and open Startup Applications Preferences.
Create an empty bash script in whichever way you prefer and enter your AutoTrash command. I created a folder called Scripts in my home directory and then an empty Bash script named autoautotrash.sh inside it.
I entered my autotrash command, saved the changes (Ctrl + W), and exited Nano (Ctrl + X).
With your command in your script, make it executable by entering the following in your favorite terminal:
In my case, this command looks like:
That’s it. From now on, whenever you log in to your desktop, your script will be one of the first things that runs, purging files from your trash and freeing up precious storage.
Now that you have emptied your trash, if you are still looking for more ways to clean up your Ubuntu machine, check this out.

Every file that we have saved on our computers has a particular extension. The file extension is added at the end of the filename followed by a dot (.). It tells the operating systems about the structure of the file so that the OS could select the right software or application to open that file. You might have seen some files on your computer that do not have any file extension or file type. How do you open such types of files? In this article, we will see how to open a file with no extension in Windows 11/10.
When it comes to opening a file on a Windows OS, there are three ways that a user can try:
Select the file you want to open and hit Enter.
To open a file, you should have the right program installed on your system. For example, if you want to open an Excel file, you should have a program that supports the excel file, like Microsoft Excel, Apache Open Office, Libre Office, etc. If you want to open a PDF file, you should have a PDF reader or a web browser to open the PDF file.
What if you come across a file with no extension? In this case, none of the above three methods work to open that file. To open the files with no extensions, first, you have to identify their extension or type. After identifying their extension, install the right program on your computer to open that file.
If you view the properties of the file with an unknown extension, you will see File as its file extension.How to open a file with no extension in Windows 11/10
