What to do when you can't uninstall an app on Windows

If you cannot uninstall an application on Windows, registry information may be affected.

The registry is a database that stores system information such as configuration information.

Every time your computer starts, it reads settings and other information stored in this registry.

Users like us rarely touch the registry. Carelessly modifying or deleting this registry may have serious consequences. Also, if the registry has been rewritten for some reason, uninstalling the application may not work properly.

In this way, there are some solutions that can be used when an application cannot be uninstalled due to the influence of the registry etc.

  • Uninstall again after restarting your computer
  • Uninstall after reinstalling the app
  • Start your computer in safe mode and try uninstalling again

Uninstall again after restarting your computer

If you cannot uninstall an application on Windows, restart your computer and try uninstalling it again.

This is because the program or related data of the application you want to uninstall may be in use.

There is also a permanent app. A resident app is an app that continues to run in the background while your computer is running.

In such cases, you may not be able to uninstall the app.

Therefore, you may be able to uninstall the program by restarting your computer and ending those programs.

Uninstall after reinstalling the app

If you can't uninstall an application, try installing the app again and then uninstalling it. The problem may be resolved.

The reason is that the registry information is overwritten when the application is installed again.

The application may not be able to be uninstalled because the registry information has changed between installation and uninstallation.

In such cases, reinstallation may overwrite registry information, allowing you to uninstall as a result.

Start your computer in safe mode and try uninstalling again

If an application cannot be uninstalled, you may be able to do so using Safe Mode.

Safe mode is primarily a diagnostic boot mode, meant to diagnose problems with your computer. Only the minimum functions necessary for diagnosis are activated.

Therefore, using Safe Mode may prevent the thing that was blocking the uninstall from starting.

[How to uninstall in safe mode]

  1. Select "Start (Windows mark)"
  2. Select "Settings (gear mark)"
  3. Select "Update & Security"
  4. Select "Recovery"
  5. Select "Restart now"
  6. Once restarted, select "Continue"
  7. Select "Advanced options"
  8. Select "Startup Settings"
  9. Set safe mode with “4” or “F4” key
  10. After booting in safe mode, uninstall the application.
