How to Fix “The Application Isn’t Responding” Error on Windows

0

Sometimes Windows software freezes. This can happen due to several reasons like old Windows version, incompatible software, driver issues, etc.

In such situations, Windows displays a pop-up window with the option to terminate the process and force close the application. It’s usually fine if it happens once or twice, but what if it keeps popping up? This article describes how to fix the “application is not responding” error on Windows 10 and 11.

USE VIDEO OF THE DAY

1. Run a System File Checker scan

Due to missing or corrupted system files, Windows applications can sometimes stop responding. In this case, you can use the System File Checker (SFC) command to check system files.

System File Checker (SFC) is a command-line utility that helps you repair corrupt system files in Windows. Follow the steps below to run System File Checker:

1. Open the command prompt as an administrator. If you are a beginner, you can use one of the many ways to open the command prompt in Windows.


2. Type the following command and press the Walk in key:

sfc /scannow

That’s all. The command line utility will start processing system files, which may take longer depending on the file. Make sure you don’t close the Command Prompt window until the verification is 100% complete.

There “sfc/scannow” will be useful if you have any Windows-related problem. Also, you should create a shortcut for System File Checker to make regular SFC checks easier.

2. Update and Repair Faulty Drivers

The rule of thumb for drivers is to leave them alone if everything is going well. However, problems can arise if the installed drivers are outdated or incompatible with your version of Windows.

If you often use software that relies on a certain driver, you may experience problems if the driver is not updated to the latest version.

For example, if you use Adobe Photoshop a lot but haven’t updated your PC’s graphics driver in years, it may crash randomly while you’re using it.

There are many useful free driver updates for Windows that can fix driver related issues. A driver updater will detect all outdated or faulty drivers and fix them with a single click. Also, if you want to go for a premium alternative, you can use Driver Booster Pro to update the drivers.

Besides using driver updates, we have also discussed many other ways to fix corrupted drivers in Windows.

3. Install the latest Windows Update

Microsoft regularly releases new updates to fix current bugs and maintain Windows stability. If you continue to receive the “application is not responding” error, updating your operating system may resolve it.


Follow these steps to update your computer to the latest version of Windows:

  1. To open the Settings app, tap the Win + I key combination.
  2. Select the Update and security option.
  3. Now click on the Check for updates button on the right side.

That’s all. If you are using an older version of Windows, it will automatically download and install the latest updates on your PC. If you encounter a download error, check the most common reasons for Windows update failure.

In addition to that, if the updates are not even showing up, here are other ways to install a Windows update.

4. Check for Memory Leaks

All apps consume a certain amount of RAM to run, but when these apps do not release or release RAM after use, it is called memory leak. In simple terms, a memory leak means the loss of available RAM in Windows.

Typically, this results in poor performance, unresponsive programs, and in the worst case, a blue screen of death (BSOD) error. If there are any memory leaks, you can use the Windows Memory Diagnostic Tool for troubleshooting.

Follow the steps mentioned below to run the utility and check for memory leaks:

  1. press the Win + R key combination to open To run dialog box.
  2. Walk in mdsched.exe and press OKAY.
  3. Select whether to perform a full scan now or when you restart the computer.

After restarting the computer, your PC screen will turn blue and scanning will start automatically. This will take over an hour, so make sure you don’t shut down your PC in the meantime.

If the tool identifies an error, you will receive the error code with solutions on the next screen. Also, if you don’t have enough RAM on your PC to handle all your daily needs, the best solution available is to upgrade your RAM.

5. Run a virus scan

If your PC is infected with a virus, it may affect the responsiveness of several applications. To fix this problem, we recommend that you install and run one of the best malware removal tools for Windows. These tools provide better and more advanced malware protection and are equipped with more features.

Once you have installed the antivirus software, you should run a full system scan to check for hidden malware including viruses. The antivirus software will automatically suggest actions after the scan is complete.

But, if you don’t want to use any third-party antivirus program, you can also scan for viruses using Windows Defender.

6. Delete temporary files

Every time you run an application in Windows, the system automatically creates unique files to store some temporary data. These files are called temporary files and they help the computer run smoothly when you use related programs or tasks.

However, cache files can take up memory. And therefore, these files can cause problems with the functioning of Windows.

So, here is how you can delete temporary files using command prompt:

1. Open the command prompt as an administrator.

2. Type the following command, then press Walk in key:

del /q/f/s %TEMP%* 

7. Launch Windows Troubleshooter

If the problem is still not solved, Windows built-in troubleshooters can help you fix the app crashing issue.

Here are the steps you need to perform to run a program compatibility troubleshooter:

  1. Hurry Win + I to open the Windows Settings app.
  2. Now click Update and security then select Troubleshoot on the left.
  3. After that select View additional troubleshooters in the right menu.
  4. Select the Program Compatibility Troubleshooter then press Run the troubleshooter.
  5. Choose the app you are having trouble with and click Next.
  6. Click on Try recommended settings then follow the on-screen instructions to complete the process.


To note: If the program you’re having trouble with is an app you downloaded from the Microsoft Store, choose the Windows Store apps convenience store to facilitate the process.

No more app crashes

In most scenarios, all you need to do is run a System File Checker scan or update to the latest version of Windows. Otherwise, you can prevent Windows from freezing on your PC by using one of the methods already mentioned above.

There are many reasons why Windows applications may become unresponsive. However, the root cause lies in the compatibility factor. When you try to run an application designed for one version of Windows on a different version, it stops responding and shows errors.
