Method 5: Refresh your Windows Installation
If none of the methods below have worked for you, it’s likely that you’re dealing with some type of underlying system corruption that cannot be resolved conventionally. In this case, the only viable fix is to reset every relevant OS component that’s related to your current Windows installation. When it comes to doing this, you have 2 ways forward:
Clean install – This is the easiest procedure you can go through since it can be started directly from the Windows menus and it won’t be required to use a compatible installation media. However, the main disadvantage is that unless you back up your data in advance, you’ll lose every bit of personal data that’s currently saved on the OS drive.Repair install – If you’re looking for a way to reset every Windows component without touching your personal files (applications, games, files, user preferences), this is it. This operation will only affect generic files related to your Windows installation. But in order to start this operation, you’ll need to insert or plug in a compatible installation media.
