What is Java executable JAR file?A JAR file is an archiving format that not only stores directories and source files and can also be run as executable files. Such Java ARchive files can contain Java class files that will run when the JAR is executed.
While Archiver tools like 7-Zip can extract content from JAR files, but doing that is pointless – we need to execute the files just as we run the EXE files.
How to run a JAR file in Windows 11/10Since Java or JAR files can’t run on Windows on their own, you need to install the Java Framework or what is popularly called Java. That said, Java files can be dependent on a particular version of Java. So the steps you need to take to open JAR files on Windows 11/10 are:
Download and install Java.
Set the System path
Run the JAVA file
Set Java file association
Establish a file association with Java runtime.
1] Download and install Java FrameworkTo run a JAR file on Windows, you need to install Java on your system. Go to Java Download Page, and install it. The default will install the latest version only. However, if your JAR file needs a different version of Java, you can download it from here.
Sometimes, an existing older version of Java can cause an issue. So, if you are facing such a problem, make sure to remove the older version first. Use the official Java Remover tool to get rid of it. Then install the latest version.
2] Set System Path for JavaNext, you need to set the JAVA_HOME path. It ensures that any JAVA file you run can find the necessary libraries for the program. You can also use the command line to echo the Java path to determine if it is correct.
3] Run a Java or JAR fileIf you have a JAR file which is not running on its own, then you can use java JDK to run it. Open Command Prompt, and type java -jar name_of_jar_file.jar. It will execute the JAR file automatically.
4] Set the Java or JAR file associationThe last step is to establish a file association with Java runtime. It will make sure that every time you run, you are not asked to select a program that can execute it.
Select ‘Choose another app.’
And then choose Select app from the computer.
You should see ‘Java(TM) Platform SE binary’ listed in this context menu but don’t select it.
Locate the file which can run the JAVA or JAR file which is available in the path we suggested above.
Make sure to check the box which says, “Always use this program.”
Once done, all future JAR files will automatically open with Java run time library. You should see the Java icon for all of these files.
How run Java JAR from command line?You’ll need to use the java command to run a .jar file
If you don’t have java installed, you can fix that by installing the default-jre package.
We hope these tips were easy to understand and were of help to open or run a Java file on Windows 11/10.

How To Open A Crdownload File On Windows 11/10
Most of you might have seen CRDOWNLOAD files while downloading video, music files, document files, etc. They are temp files created by Chrome when you download a file. In fact, they are created by all Chromium-based browsers.
When the browser starts downloading a file, it first tags .crdownload file extension to the filename and removes it once the download is completed. This article discusses how crdownload files are different from other files and how to open it on your browser.
What is a CRDOWNLOAD file?Crdownload file is a partial or incomplete file commonly known as Chrome partial download files. They are temporary files created during the download process, and they can be used as a regular file once the download is complete. In simple words, Chrome creates crdownload files during the download process and removes the attached crdownload file extension when the download is finished.
Crdownload means “Chromium download”. This file extension is specific to Chromium-based browsers like Google Chrome – and even Microsoft Edge Chromium now.
Related: Download is in progress says Chrome; But nothing is downloading.
How to open CRDOWNLOAD files?Crdownload files are partial download files and they are of no use until your browser finishes the downloading process. To fully use these files, you need to resume the download process and delete the ones that are useless.
To open a Crdownload file:
Launch your browser and go to the download page.
Locate the files that have paused downloading.
Resume the downloading process or start the fresh download again.
If all the files you download are paused and have the crdownload file extension, it could mean there is an issue with your Chrome.
In such a case, make sure that your internet connection is good and update your browser to the latest version.
You cannot see a crdownload while downloading a file in the browser. However, you can view them in the folder where you are saving the file. As mentioned earlier, crdownload files are incomplete files. If you see files with .crdownload extensions, it only means that Chrome is either still downloading the file or it suggests the download has been interrupted.
If the download has stopped, it is possible to use a part of the file by removing the crdownload extension from the file name.
For example, if there is an incomplete file named audiofile.mp3.crdownload, you can use a part of the sound file by removing .crdownload extension and renaming it as audiofile.mp3. You can now open and use the file in an mp3 player, although the download is still incomplete. Similarly, if you are downloading an AVI file, you can use a part of the sound file by removing .crdownload extension. You can then open and use the file to play video in a VLC player as long as your browser continues to download the file.
You can open and use crdownload files of audio and video only in the programs for which you are downloading. You cannot use documents, archives, images, etc in the crdownload extension. It is worth noting that you cannot convert a crdownload file to other formats like Avi, mp4, or pdf as they are incomplete files.
That’s all.

How To Disable Startup Services On Windows 11 Or 10
If you no longer need a service to run at startup, suspect it is malware, or prefer it to run only when you need it, you can disable it. Here’s a quick tutorial on how to disable services from running at startup on Windows 11 or Windows 10.
See also: 30+ Windows 11 Services to Disable for Gaming Performance
A Windows service is a program that operates in the background to make things work. Similar to startup programs, there is a list of services that will run during the startup of your Windows PC. Most of these services are important and mandatory for Windows to work.
However, some programs have their own services set to run during Windows startup and continue to run in the background as you use your computer. These services are usually required for their corresponding programs or software to work properly. This is also why, even after you’ve stopped a program from running at startup in Task Manager, that particular program would still run during startup because it has a corresponding service that automatically starts it up.
Disabling a service that a program relies on will cause the program to stop working or give errors when you run it. While some of these services can be malicious or unknown, it’s best to uninstall the corresponding program that you suspect to be the culprit of your problem than to disable its service.
If you insist on disabling a service from running at startup, make sure that particular service is not a Microsoft service that Windows relies on to function properly. If you accidentally disable any of these crucial Windows-related services, you could possibly brick your Windows. But don’t worry, we will show you how to hide the sensitive Windows-related services in the tutorial below so that you don’t accidentally disable any of them.
To stop any service from running at startup on Windows 11/10, follow these steps:
Go to start menu (or press Win+R keys), type in MSCONFIG and open it.
Recommended: Check the checkbox that says “Hide all Microsoft services“. Doing so will hide all sensitive and important Microsoft services so that you don’t accidentally disable any of them and end up bricking your PC.
To disable a service from running at startup, simply uncheck the checkbox next to its corresponding service.
Services listed in the MSCONFIG window are all the services that would run at startup on your Windows PC. Usually, you will know what a service does by looking at its corresponding manufacturer. For example, if you have Apple devices and iTunes installed on your PC, you should be able to see several services related to it with the manufacturer shown as Apple Inc.
Before disabling any service, it’s important to understand what it does and how it affects your system. You can usually find this information by looking up the service name online. Microsoft’s Service Database is a good place to start.
Another way to determine which services to disable is to use the Task Manager’s “Startup” tab. This tab lists all the programs that start with Windows and provides information about their impact on system performance. If a program has a high startup impact, disabling its associated service may help improve system performance.
While MSCONFIG is a useful tool for managing startup services, there are other ways to do it as well. One alternative is to use the Services app, which provides a more detailed view of each service and its properties. To open the Services app, type “services.msc” into the Start menu or Run dialog box.

File History is a powerful backup feature in Windows 11. To be more precise, it is an automatic backup feature that will back up your user folder libraries to a selected external USB storage device. It also keeps a history of file versions for users.
With File History enabled, you’ll have alternative backup versions of your files available. Then you can select to restore previous versions of files preserved by the File History feature.
Although you’ll probably rarely need to restore backup versions of files, it’s a good idea to keep backup copies for them with File History, just in case.
You can enable and disable File History with the methods outlined in the text below.
Is File History a new Windows 11 feature, and where can I find it?File History isn’t something new in Windows 11. Microsoft originally introduced File History in Windows 8 as an alternative to Backup and Restore. It’s a better utility for backing up user folders than Backup and Restore.
However, some users have been a little confused by the absence of File History options in Windows 11’s redesigned Settings app. Windows 10 includes options for enabling and configuring File History via Settings, which isn’t available in 11.
The only backup options you can configure in Windows 11’s Settings app are for OneDrive. You can set up the OneDrive folder syncing via Accounts, then Windows backup in Settings. That cloud sync feature backs up folders and files to OneDrive.
Don’t worry, File History still exists in Windows 11! However, you’ll need to activate that legacy feature via the Control Panel now. Alternatively, you can also enable and disable it with the two other methods below.
How can I turn on Network Discovery for File History?Keep in mind that you’ll need to have Network Discovery enabled in order to utilize File History in Windows 11.
If it’s not enabled, File History’s Turn on button will be grayed out in the Control Panel. This is how you can turn on Network Discovery in Windows 11:
How can I turn on and off File History in Windows 11? 1. Use the Control Panel1. Open Windows 11’s search box by pressing the magnifying glass taskbar button on your desktop. Alternatively, you can press the Windows key on your keyboard.
2. Type the word File History within the search box.
3. Select File History from the results to open the Control Panel applet.
Expert tip:
6. To select an external drive to back up files on, insert a USB storage device in your PC.
8. Press the OK button to confirm your chosen storage device.
2. Use the Group Policy EditorNOTE
Group Policy Editor is not available in Windows 11 Home edition. You can utilize Group Policy Editor within the Pro and Enterprise editions of the platform.
3. Edit the registry What can I do if File History doesn’t work?If File History still doesn’t work with Network Discovery enabled, make sure that Network Discovery stays on as it should.
Even more, the service for that feature might be disabled. Thus, the solution might be to enable the File History Service. You can check that service as follows:
How can I restore my files with File History?When File History has preserved some backup copies, you can restore previous file versions any time you fancy. To do so, open the File History Control Panel applet as outlined within the first three steps of the first resolution for activating the backup feature.
Although there are plenty of third-party backup utilities for Windows, File History is perfectly sufficient for preserving copies of user files. It’s a convenient feature that will automatically back up your user folders at specified intervals.
Don’t think you won’t ever need backup file copies. There are all sorts of ways user files can become corrupted or get accidentally deleted. So, it might be better to be safe than sorry by enabling and utilizing File History in Windows 11.

Disk Error Checking: How To Run Chkdsk In Windows 11/10
Users of Windows 11/10/8 may have noticed that Disk Error Checking is a bit different from the earlier versions of Windows. Checking your hard disk, every once in a while for errors – usually caused due to improper or sudden shutdowns, corrupted software, metadata corruption, etc., – in Windows 7 and earlier is always a good practice as this can help solve some computer problems and improve the performance of your Windows computer.
Disk Error Checking in Windows 11/10Microsoft has redesigned chkdsk utility – the tool for detecting and fixing disk corruption. Microsoft introduced a file system called ReFS, which does not require an offline chkdsk to repair corruptions – as it follows a different model for resiliency and hence does not need to run the traditional chkdsk utility.
The disk is periodically checked for file system errors, bad sectors, lost clusters, etc., during Automatic Maintenance and you now no longer need to really go and run it. In fact, Windows 8 now even exposes the state of the file system and disk via the Action Center or under the Drive properties in File Explorer. If potential errors are found, you will be informed about it. You can continue to use the computer while the scan is carried out in the background. If errors are found, you may be prompted via a notification to restart your computer.

Windows found errors on this drive that need to be repairedYou may sometimes see a message – Windows found errors on this drive that need to be repaired. If you see it, you may want to run a scan manually. Earlier, you had to schedule Disk Error Checking for the system drive and for drives that had files or processes or folders opened. In Windows 11/10, error checking starts right away, even on the system drive – and it longer needs to be scheduled at start-up. Only if some errors are found, will you have to restart to let Windows 11/10 fix the errors.
How to run CHKDSK in Windows 11/10The scanning starts. I found that the process ran quite fast and the scanning was over in less than 5 minutes.
On completion, Windows will display a message. If no errors are found it will say so.
If errors are found, you will see the following message:
Restart your computer to repair the file system. You can restart right away or schedule the error fixing on the next restart.
In Windows 11/10, Microsoft has made the Disk Error detection and correction of file system errors less intrusive so that users can carry on working on their computers without worrying about such error.
To run Check Disk on your System Drive (C), using the command line, type the following and hit Enter:
chkdsk
/f C:If required, restart your computer.

Will chkdsk fix corrupt files?No, CHKDSK will not fix corrupt or damaged files. It only checks if the file system is in good condition and that the data on the disk is in a consistent and safe state. If files are damaged, the CHKDSK attempts to separate the damaged files and save the remnants in .chk file format.
