The application is not responding

Application Or Program Is Not Responding/Stopped Working. How To Fix It?

You may have encountered a problem whereby you receive a Windows notification stating that a program is not responding. For example, "The application is not responding", or a similar message such as "The program has stopped working". This message can appear with any program, and often with three options (depending on the Windows version): close the program; wait for it to respond, and; check for a solution and restart the program.

In most cases, closing the program allows you to bypass the notification but not to solve the problem itself (you receive the same message when trying to run the program). You can wait for the program to respond, but in most cases, it will not respond after an extensive period and keeps the "The application is not responding" message open, which you can close only by using Windows Task Manager or restarting the computer.

This problem usually occurs when your computer is infected with malware, there are conflicts between two (or more) programs, there is a lack of computer resources, or system/program files or registry entries are corrupted. To solve this problem, you might need to run System File Checker, run a performance diagnostic tool, scan your system for malware, reinstall a program, update Windows, perform a clean boot, or run the DISM tool. In this guide, we show how to apply these methods to resolve the "The application is not responding" notification. Bear in mind that these are general solutions and might not work with all programs.

Perform A Clean Boot

When you start Windows using a normal startup operation, several applications and services start automatically, and then run in the background. These programs include basic system processes, antivirus software, system utility applications, and other software that has been previously installed. These applications and services can cause software conflicts. A clean boot is performed to start Windows using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or update. It is possible that one or more installed programs is interfering with the program that causes the "The application is not responding" problem. Performing a clean boot might help you to ascertain if this is the case. To perform a clean boot, type "system configuration" in Windows Search and click the "System Configuration" result.

perform a clean boot step 1

In the System Configuration window, you will see five tabs: General, Boot, Services, Startup, and Tools. In this method, we use Services and Startup tabs. First, click the "Services" tab and tick the "Hide all Microsoft services" checkbox. All Microsoft services will be hidden and only third-party services remain. Now click "Disable all" to disable all non-Microsoft services.

perform a clean boot step 2

Now click the "Startup" tab and then click "Open Task Manager".

perform a clean boot step 3

Under the Task Manager Startup tab, select all enabled applications and disable them one-by-one by selecting each application and clicking the "Disable" button. Once all programs are disabled, close Task Manager and click "OK" in the System Configuration Startup tab. Restart the computer and check if the particular program is still causing the "The application is not responding" notification.

perform a clean boot step 4

If the program now works and the notification no longer occurs, you will need to determine which program was interfering with it. This can be done by enabling the disabled programs one-by-one. If you find a problematic program, consider uninstalling it.

Scan Your System For Malware Or Viruses

It is possible that a virus or malware infection is preventing some programs from working properly and causing the "The application is not responding" issue. We recommend that you scan your system using antivirus software. You can use Windows Defender (a built-in antivirus program), which protects the computer against viruses, spyware, and other malicious software. Alternatively, you can run third-party antivirus software if you have this installed. To run a full system scan using Windows Defender, type "virus" in Search and click on the "Virus & threat protection" result.

scan your system for malware and viruses step 1

In the Virus & threat protection window, find and click the "Run a new advanced scan" option.

scan your system for malware and viruses step 2

You will see three scan options: Full, Custom, and Windows Defender Offline. We recommend that you choose "Full scan", which will check all files and programs running on your hard disk. Note that it will take some time (usually over an hour). To start a Full scan, click "Scan now" when the "Full scan" option is selected.

scan your system for malware and viruses step 3

If you have third-party antivirus software installed, you can use that rather than Windows Defender. Alternatively, choose a virus and malware scanner from our Top anti-malware list. The list consists of well-known top spyware removers and will help you choose the right software for your computer's protection. You can find the list by clicking this link

Run System File Checker

System File Checker is a Windows utility that allows users to scan for corruptions in system files and restore them. This guide describes how to run the System File Checker tool (SFC.exe) to scan system files and repair any missing or corrupted ones. If a Windows Resource Protection (WRP) file is missing or corrupted, Windows may not behave as expected. For example, some Windows functions might fail or Windows will crash. The "sfc scannow" option is one of several specific switches available with the sfc command, the Command Prompt command used to run System File Checker. To run Command Prompt, type "command prompt" in Search, right-click on "Command Prompt", and select "Run as administrator" from the drop-down menu to run it with administrator privileges.

run system file checker step 1

When you select "Run as administrator", a User Account Control prompt will appear asking if you would like to allow the Command Prompt to make changes to your computer. Click "Yes".

run system file checker step 2

In the open Command Prompt window, type the "sfc /scannow" command and press Enter on the keyboard to execute it. System File Checker will start and should take some time to complete the scan (about 15 minutes). Wait for the scanning process to complete and restart the computer.

run system file checker step 3

If the SFC scan does not fix the problem, or you could not run the SFC scan, run a Deployment Image Servicing and Management (DISM) scan and then try to run the SFC scan again. DISM can be used to repair and prepare Windows images, including the Windows Recovery Environment, Windows Setup, and Windows PE. To run a DISM scan, open Command Prompt as administrator and type this command: "DISM /Online /Cleanup-Image /RestoreHealth". Press Enter on the keyboard to execute it.

run system file checker step 4

Temporarily Disable Your Antivirus Software

We recommended that scan the system for malware and viruses, however, you can also try to temporarily disable the antivirus software. It is possible that the installed antivirus software is interfering with the program and causing the "The application is not responding" problem. To verify whether the installed third-party antivirus software is not the culprit of this problem, we recommend that you temporarily disable it. Then launch the program again and check if the problem persists. If disabling (or uninstalling) the antivirus software helps, you could switch to another product or reinstall the currently-installed software. If you are not sure how to disable antivirus software, read this guide in which you will find instructions on how to disable some of the most popular antivirus programs.

Check For Registry Issues

If there are registry corruptions, missing shared DLL's, unused file extensions, ActiveX and Class issues, obsolete software, etc., you can scan for issues using CCleaner software and fix them.

CCleaner is a small, effective utility for computers running Microsoft Windows. It cleans junk and issues that accumulate over time: temporary files, broken shortcuts, and other problems. It protects privacy, cleans browsing history and temporary internet files, allowing you to be a more confident internet user and less susceptible to identity theft. CCleaner can clean redundant files from various programs, thus saving hard disk space, remove unneeded entries in Windows Registry, help uninstall software, and select which programs start with Windows. You can download CCleaner from here

When downloaded, install CCleaner and open it. Select "Registry" on the left pane and click "Scan for Issues". It will find any registry issues on your computer. To clean or fix them, click "Fix selected Issues...". Close CCleaner when finished and check if the "The application is not responding" problem persists.
