But keep in mind that this is not a fix as it only hides the issue rather than resolve it.

Method 4: Refreshing every Windows Component

If none of the other potential fixes above have worked in your case, the last thing you can do is to ensure that every component used by your Windows installation is refreshed so that every corrupted instance is removed. A lot of affected users have confirmed that this was the only thing that allowed them to fix the problem.

So when it comes to resetting every Windows component, you really have 2 viable options:

  • Clean installing – If you’re looking for a quick fix and you already have your data backed up, this should be the option in your case. Keep in mind that a clean installation procedure will not require you to use compatible installation media, but the major drawback is that your C:/ drive along with every bit of personal data will be wiped.
  • Repair installing – This should be the approach if you want to keep your personal files, applications, and other user preferences. However, keep in mind that you’ll need to use an installation media of your Windows version plugged in via USB or inserted via DVD.
