Suggested March 2024 System & User Environment Variables In Windows 11/10 Explained

System and User Environment Variables has always been a complex topic of discussion for day-to-day Windows OS users. What do they do? A tutorial on the internet said to add a PATH variable, but what is it? Where do I find these variables? All of these questions will be shortly answered in this post. We’ve tried to give you a high-level overview of what System and User Environment Variables are and how you can utilize them.

In this post, we will discuss Environment Variables, System and User Environment Variables and how to add and modify them. Then we will move on to Dynamic System Variables and see how to use them in the command prompt.

What is an Environment Variable In Windows OS

Environment Variable is formed up by two separate words, ‘Environment’ and ‘Variable’. Let’s discuss ‘variable’ first. It means that the entity can store a value and vary from computer to computer. Windows provide an ‘Environment’ for applications to execute and perform operations and that is what makes the first word. Combining both, Environment Variables are those dynamic objects that store the values provided by the environment. Now environment provides values that help other programs in obtaining some crucial information about the system. Like there is an environment variable called ‘windir’ that corresponds to the directory where Windows is installed. To see this in action, open up an explorer window and type in ‘%windir%’ in the address bar. The Windows installation folder will open up.

Very similarly, you can make reference to the Windows directory using ‘windir’ variable in other programs and scripts. There are numerous other variables that can be accessed, ‘TEMP’ or ‘TMP’ is the variable that points to the directory where all temporary files are stored. The most popular, ‘Path’ variable is the one that points to the directories containing executable files. So that you can run a program from the Command Prompt in any other directory. We’ve explained Path later on in this post. All these variables come in handy when you are developing something or using the shell a lot.

What are System & User Environment Variables

Very similar to how the Registry works on Windows, we have System and User Environment Variables. The system variables are system-wide accepted and do not vary from user to user. Whereas, User Environments are configured differently from user to user. You can add your variables under the user so that other users are not affected by them.

Just for your information since we are discussing the topic in depth. System Variables are evaluated before User Variables. So if there are some user variables with the same name as system variables then user variables will be considered. The Path variable is generated in a different way. The effective Path will be the User Path variable appended to the System Path variable. So the order of entries will be system entries followed by user entries.

How to add & modify Environment Variables

A small warning before we go deeper. Create a system restore point, and try not to tamper with the existing settings configured for your system. Until unless you are very sure about your actions. To open the ‘Environment Variables’ Window, follow these steps:

Now in this window select ‘Advanced System Settings’ from the left part.

Hit the last button saying ‘Environment Variables’ to open our destined window.

Once you’ve opened this up, you will be able to view User and System variables separately. The variable name is in the first column and its value in the second. The corresponding buttons below the table let you ‘Add’, ‘Edit’ and ‘Delete’ these variables.

Using the Path variable

Path is the most used environment variable. As I mentioned, it points to directories that contain executable files. Once you’ve correctly setup your Path variable, you can use these executables from anywhere in the system. Let’s try to understand this with an example. Open up the environment variables window and look for ‘Path’ in system variables.

Now to run your application, open up Command Prompt and type in the name of the executable file that was in the folder. You can provide additional arguments if the program supports it. The program will run from the command prompt without actually being in the directory from where you executed the command. That is the beauty of the Path variable.

List of all Environment Variables

Open command prompt and type ‘SET’ and hit Enter. The entire list of variables with their current values will be displayed and you can refer to it for making changes to your computer.

Dynamic Environment Variables

Unlike, conventional variables, dynamic environment variables are provided by the CMD and not by the system. You cannot change the values of these variables and they expand to various discrete values whenever queried. We usually use these variables for batch processing and these are not stored in the environment. Even the ‘SET’ command will not reveal these variables. Some of the dynamic environment variables are listed below.

Java System Nanotime() Vs System Currenttimemillis

What are the Time Operations in Java?

There are two time operations provided by Java environment. For the time related operation, users can use these operations.



System.nanoTime() mainly known as expensive call, used to get more specific value of time. And, System.currentTimeMillis() most authentic possible passed time, helps to get the time value based on the operating system basically. The first function returns the time value in Nano Seconds (can give negative value sometimes) and on the other hand second function in milliseconds. So it’s obvious, System.nanoTime() is one step ahead and more acceptable for its accuracy.

What are System.nanoTime() and System.currentTimeMillis()

The System.nanoTime() method in Java Environment helps to find the difference out at two pointers.

In simple words, it helps to get a time reading before the process starts and another after executing the method.

It is not recommended every time to profile a code because the time may differ based on the OS of a system. So, we can experience some inaccuracy.

The System.currentTimeMillis(), is a thread safe method which will no return ambiguous results.

This function returns date, time and year as time.

Where the reference is fixed, there we can get accurate output. But when a user make some changes in system time, it will give wrong results at that moment.

Algorithm for System.nano.Time()

Step 1 − Load Libraries.

Step 2 − Declare Main Method by Using System.nanoTime().

Step 3 − Display The Table Of 2.

Step 4 − The Loop Will Produce Multiple of 2 (2x Multiple).

Step 5 − Print Output from the given Input.

Algorithm for System.currentTimeMillis()

Step 1 − Load Libraries.

Step 2 − Declare Main Method By Using TimeMillis() Method.

Step 3 − Display the Milliseconds, Minutes, Hours and Days.

Step 4 − Print Output.

Syntax for System.currenyTimeMillis() System.currentTimeMillis(); Syntax for System.nanoTime() public static long nanoTime() long process startTime = System.nanoTime(); long process estimatedTime = System.nanoTime() - startTime; Comparison of System.nanoTime() and System.currentTimeMillis():-

Here is a general example for the two specific Java time operations –

package javalangtimeslot; import java.lang.*; public class javatimeslot { public static void main(String[] args) { System.out.print("Time in nanoseconds we can see here = "); System.out.println(System.nanoTime()); System.out.print("Time in milliseconds we can see here = "); System.out.println(System.currentTimeMillis()); } } Output Time in nanoseconds we can see here = 4083437933186033 Time in milliseconds we can see here = 1680778649732 Different Approaches to Follow

Approach 1 − Java Program using System.currentTimeMillis() Method

Approach 2 − Java Program using Java System.nanoTime()

Java Program using System.currentTimeMillis() Method

System.currentTimeMillis() Method return current time in milli second unit. This method times how much time a part of a code takes to execute.

Example 1 import*; public class timefuncjava { public static void main(String[] args){ System.out.println("Milliseconds Are Here : " + System.currentTimeMillis()); System.out.println("Seconds Are Here: " + (System.currentTimeMillis())/ 2000); System.out.println("Minutes Are Here: " + (System.currentTimeMillis())/ 2000 / 120); System.out.println("Hours Are Here: " + (System.currentTimeMillis())/ 2000 / 120 / 120); System.out.println("Days Are: " + (System.currentTimeMillis())/ 2000 / 120 / 120 / 48); System.out.println("Years Total: " + (System.currentTimeMillis()) / 2000 / 120 / 120 / 48 / 365); System.out.println("Milliseconds Are Here : " + System.currentTimeMillis()); System.out.println("Seconds Are Here: " + (System.currentTimeMillis())/ 2000); System.out.println("Minutes Are Here: " + (System.currentTimeMillis())/ 2000 / 120); System.out.println("Hours Are Here: " + (System.currentTimeMillis())/ 2000 / 120 / 120); System.out.println("Days Are: " + (System.currentTimeMillis())/ 2000 / 120 / 120 / 48); System.out.println("Years Total: " + (System.currentTimeMillis()) / 2000 / 120 / 120 / 48 / 365); } } Output Milliseconds Are Here : 1680778875055 Seconds Are Here: 840389437 Minutes Are Here: 7003245 Hours Are Here: 58360 Days Are: 1215 Years Total: 3 Milliseconds Are Here : 1680778875062 Seconds Are Here: 840389437 Minutes Are Here: 7003245 Hours Are Here: 58360 Days Are: 1215 Years Total: 3

Here in this build code we have used the TimeMillis to get milliseconds, seconds, minutes, hours, days and years.

Example 2 public class timeprogjava{ public static void main(String args[]){ long starting, ending; System.out.println("Timing a loop from 0 to 100,000,000,000"); starting= System.currentTimeMillis(); for(long k=0;k<100000000000L;k++); ending=System.currentTimeMillis(); System.out.println("Elapsed time Is: "+(ending-starting)); } } Output Timing a loop from 0 to 100,000,000,000 Java Program using System.nanoTime() Method

System nanoTime() Method is a Java Environment, which is a high definition time pool in the nano second unit. This method always returns current value.

Example 1

Using nano Time() -difference, we can calculate the consumed time by an empty loop to run this for the next 1000 times. Thee time output we will get before and after of the loop.

public class javacodetime { public static void main(String args[]) { long nanoTime2 = System.nanoTime(); for(int k=0; k < 10000; k++) { } long nanoTime5 = System.nanoTime(); long runTimeInNanoSeconds = nanoTime5 - nanoTime2; System.out.println("Time taken to execute the process by for loop : " + runTimeInNanoSeconds + " nano seconds"); } } Output Time taken to execute the process by for loop : 132509 nano seconds Example 2

This example will help us to get the current time by using System.nanoTime() method in nano seconds.

public class javatimecode { public static void main(String args[]) { long nanoTime = System.nanoTime(); System.out.println("Current time as in Nano Seconds : "+nanoTime); } } Output Current time as in Nano Seconds : 4084089973012410 Conclusion

In conclusion, the chúng tôi Time() method is required to use when the problem is too heavy. For the fast performance like HD games, the nano time operation is the best option to avail. But for the accurate output we can use System.currentTimeMillis().

In this article we have learned how to get the time by using the two time methods. We also built some Java code by using the logic.

High graphical presets will need a $1,000 pre-built PC or equivalent for 1080p, a $1,500 pre-built gaming PC is needed for 1440p gaming, and finally, a $2,000 pre-build if you want to play at 4K.

The System Cannot Find The Drive Specified

According to some users, after resetting the computer from a USB, while accessing a drive from the Command Prompt, when trying to open a folder in a drive, or just doing anything related to the hard drive, the following error message pops up.

The system cannot find the drive specified

This error message, sometimes, comes alongside or after ERROR_INVALID_DRIVE Code 15.

What is The system cannot find the path specified error?

You may see Error 15 or the error message in question when trying to access a particular drive or a folder in that drive. What is happening here is that your computer is unable to fetch that drive even though it is plugged into your system. The error message has been notified both when trying to access the file manually or when doing the same via the Command Prompt.

There are various reasons why this could happen, the following are some of the most common ones, but the list is not exhaustive.

Corrupted disk or system files.

A malware or virus attack

Conflicting software.

Lack of permissions

We have already seen how to resolve The system cannot find the file specified error, now here, we will be talking about the reasons and solutions for a similar but more specific error The system cannot find the drive specified.

Fix The system cannot find the drive specified

If you are seeing the “The system cannot find the drive specified” error message on your Windows 11/10 computer, first of all, update your computer, and if the issue persists, try the following solutions to resolve it.

Restart your computer

Run ChkDsk

Fix for Shared Drive (if applicable)

Give permission to the drive or file

Reinstall/Update disk drivers

Let us talk about them in detail.

1] Restart  your computer

First up, try restarting the computer. If the problem is because of a glitch, restarting is the easiest and the best way to fix it. So, do that, and check if the issue persists. In case, restarting is to no avail, move to the next solution.

2] Run ChkDsk

Next up, we need to run a command to check the health of the disk and possibly repair it. To do that, open the Command Prompt as an administrator and run the following command.

Chkdsk C: /f

Replace C with the letter of the drive that’s giving you the trouble.

After executing the command, wait for it to complete the process, hopefully, your issue will be resolved.

3] Fix for Shared Drive (if applicable)

If you are not facing this issue on a shared drive, skip this solution. But according to some users, the mapped drive when opened in the elevated mode is showing the error message in question. The problem is related to UAC or User Account Control. We will be using the Registry Editor or Local Group Policy Editor to fix this issue.

Open Group Policy Editor from the Start Menu and go to the following location.

If you have Registry Editor, open it, and go to the following location.


Finally, restart your computer and check if the issue persists.

4] Give Permission to the file or drive

If you are getting ERROR_INVALID_DRIVE then try giving permissions to the file or the drive. Follow the given steps to do the same.

Now, restart your computer and try accessing that drive.

5] Reinstall/Update disk drivers

First, you need to uninstall the disk drivers and then reboot your computer. On boot, Windows will automatically reinstall the disk drivers. Check if the issue is resolved, otherwise, you can try updating the disk drivers and see if that helps.

Hopefully, these solutions will do the trick for you.

Read: Restoration Incomplete Recovery Manager error on Windows

Why is my drive not available?

If your external hard drive is not showing up or detected or not available in Windows 11/10, then you should plug it in another port and check again. The problem can also occur if external device drivers are not updated or USB selective suspend setting is enabled. In such a case, you should update external device drivers, disable USB selective suspend setting, and enable and format the drive using Disk Management.

How do you resolve The system cannot find the file specified?

If you see The system cannot find the file specified error for a system file or device on your Windows 11/10 system, then you can resolve this error by running the SFC Scan, identifying and re-installing the driver using the INF file, etc. If you see this error just after logging in to your computer, then maybe one of the Startup apps is missing the required file. In such a case, you should troubleshoot in Clean Boot State or check the error log in the Event Viewer to get some more information to solve the issue.

Hope this helps.

How To Get System Diagnostic Files On Macos

Sometimes when your Mac is doing things you can’t explain, such as in the presence of a bug in macOS, you have no other choice than to report the bug to Apple.

Many times, the support staff are going to ask you to provide Apple’s engineers with what’s known as a sysdiagnose, which is a special screenshot of your system information and performance at that very moment in time. This information is very useful for bug reporting and troubleshooting as it allows Apple to try and reproduce issues so they can fix them.

In this piece, we’ll explain what a sysdiagnose is, what it contains, and how to grab one so you can file a proper bug report to Apple when you have issues with your Mac.

What is a sysdiagnose?

Apple often requests a sysdiagnose whenever you report a bug via Apple’s bug reporter because they need to know everything that was having an effect on your system at the time of the bug so they can reproduce the issue. Without being able to reproduce the issue, Apple engineers will very seldom know what you’re talking about or have any clue as to what could be causing that specific issue.

A sysdiagnose is essentially a screenshot of your Mac’s state at a particular period in time. It’s not an image file like a traditional screenshot is though; it’s actually a harvest of information, such as what apps were running at the time of the incident, computer resource usage, and much more. As Apple notes on their developer website, the following information is included in a sysdiagnose:

What sysdiagnose Collects:

• If a specific process is supplied as an argument: data about the virtual memory regions allocated in the process

How to grab a sysdiagnose on your Mac

A sysdiagnose is very simple to grab on any Mac. You’ll want to grab a sysdiagnose either while a problem is occurring or immediately after a problem occurs for the best results. To do so, you’ll follow these steps:

1) As the problem is occurring, or after it occurs, press the Shift ⇧ + Control + Option + Command ⌘ + Period . keys all at once.

2) Your screen will appear to flash, just as it would if you were taking a screenshot on your iPhone, iPod touch, or iPad. This is your Mac taking a ‘screenshot’ of your system at that point in time.

3) Wait patiently as your Mac collects and compiles this information into your sysdiagnose archive file. This can take anywhere from 15 seconds to 2 minutes, depending on the speed of your Mac.

4) When complete, a new Finder window should launch with focus on the “tmp” folder. You should see your most recent sysdiagnose selected in the window.

5) You can now drag this sysdiagnose file to your desktop, or anywhere else it can be more easily accessed so you can share it with Apple.

Who to share a sysdiagnose with

Typically, you would only have to supply this kind of information to Apple if they ask for it. I wouldn’t recommend sending this kind of information off to any third-party app developer or average Joe that you didn’t know very well because there’s a lot of sensitive information contained in these files that could put your privacy or security at risk.

What kinds of information, you ask? – Oh, you know, just the general run-of-the-mill serial number information and identifiable personal computer information that could be used maliciously.


Grabbing a sysdiagnose can be one of the quickest and easiest ways to help Apple in responding to one of your bug reports in a positive way. Without one, they won’t have much of a clue as to how to reproduce your issues, so it’s a really handy tool for this purpose.

The System Image Restore Failed, Error Code 0X80042407

In this post, we will describe the possible solutions for The system image restore failed, error code 0x80042407 error which you may see when you try to create or restore a Windows System Image. The most common causes of this error are:

Restoring Windows from the system image on a different hard disk or computer of different architecture.

The destination drive has less space than the original hard drive from which the image is created.

If you are experiencing the same error on your system, this post may help you get rid of the problem.

The disk that is set as active in BIOS is too small to recover the original system image, Replace the disk with a larger one and retry the restore operation, Error Code 0x80042407.

The system image restore failed, error code 0x80042407

If you see System Image error code 0x80042407, try the following troubleshooting methods to fix this error:

Use the drive of the same size.

Shrink the source partition.

Remove all the partitions.

1] Use the drive of the same size

If you are using the system image backup to restore Windows on another computer or drive, make sure that the drive on which the backup is to be restored should have the space equal to or greater than the size of the drive from which the backup image is created.

Let’s understand it with an example. Let’s say, the image file that you have created has a size of 70 GB and the drive from which you have created it has a size of 500 GB. If you restore it on a drive with less than 500 GB of space, say 300 GB, you will get this error.

Do note that when you create a disk image, the system compresses it. That’s why the size of the system image file is always less than the size of the original disk. Hence, it does not matter what the size of the system image file is, you should always keep the size of the original drive in mind while restoring the system image.

2] Shrink the source partition

If the destination drive has less space than the original drive (the drive from which you have created the image), you can try shrinking the source partition to a size less than the destination drive, then create its image. Now, use this image file to restore Windows. If you are restoring the image on SSD, try to clone the shrunk partition to the SSD.

The steps to shrink the drive are given below:

3] Remove all the partitions

You may be receiving this error because the drive on which you are restoring the system image has less space than the original drive from which you have created the image. If it is possible for you, you can try to remove all the partitions from the destination drive and then restore the system image.

Deleting all the partitions can help because it will increase the size of the hard drive for system image restore. Do note that this method will not work if the size of the destination drive (including all the partitions) is less than the size of the drive from which you have created the image.

Hope something helps.
