Solution 2 – Try updating your system
For starters, you should try and check for updates right away. Maybe the diligent Microsoft developers have prepared a fix and it is waiting for you to get it. To check for new KB (Knowledge Base) update, do as follows:
- Open Search Windows and type Windows Update.
- Click Check for updates.
- If there are some updates available, the system will install them after Active hours.
Have in mind that this will work only if there are no corrupted system files. If the problem persists, move on to a next step.
Solution 3 – Check Windows for corruption
As we all know, updates are installed and stored on the system partition. Moreover, possible malware infection thrives on playing with those essential files. So, the files can get corrupted or deleted. As the matter of fact, they start working against you. So, we should check them out.
The first step you should take is scanning all partitions with Windows Defender or third-party antimalware software. Additionally, you’ll want to check files’ integrity with the command prompt. And this is the way to do it:
- Press Windows Key + X to open Win + X menu. Now select Command Prompt (Admin) or PowerShell (Admin) from the list.
- Now enter sfc /scannow and press Enter.
SFC scan will now start. This scan can take about 15 minutes, so don’t interrupt it.
If you are unable to run SFC scan, or if the SFC scan didn’t fix your problem, you need to use DISM scan instead. To do that, start Command Prompt as administrator and run DISM /Online /Cleanup-Image /RestoreHealth command.
DISM scan might take 20 minutes or more, so don’t interfere with it. Once the scan is finished, check if the problem is resolved. If the issue is still present, repeat the SFC scan again to fix the problem.
