F8 key.

**Step 2:**I would recommend you to place the computer in clean boot and then check if the issue persists.

Note: ****After troubleshooting, make sure to put the computer to start as usual as mentioned in Step 7 in the above KB article.
If the issue doesn’t persists when the Computer is in clean boot or while in the Safe Mode with Networking, then the issue is confirmed to be caused by a certain non-Microsoft
applications.
Method 3:
Viruses are also known to cause these kinds of issues. Please scan your computer from
Microsoft Safety Scanner, which would help us to get rid of viruses, spyware, and other malicious software.
The Microsoft Safety Scanner is a free downloadable security tool that provides on-demand scanning and helps remove viruses, spyware, and other malicious software. It works with
your existing antivirus software.
