What tool is used to troubleshoot problems with Windows?

By default, users use the built-in troubleshooter in Windows, which you can access by doing the following:

  1. Press Windows key + S and enter troubleshoot. Select Troubleshoot settings from the menu.
  2. Click on Additional troubleshooters.
  3. Now select the troubleshooter that you want to run.

Using Windows Troubleshooter is sometimes the best choice because it doesn’t require downloading and installing any additional software.

Remember that this feature is designed to only run on local computers. So if you want to fix a PC remotely, you might need to use remote troubleshooter software instead.

If you’re dealing with more serious issues, we recommend using PC repair tools since they offer better features for advanced problems.

Hopefully, we helped you narrow your choices for a Windows PC optimizer troubleshooting tool because they are great assets for a performant device.
