How to use Clean Boot in Windows 11 to identify problematic third-party software?

Hello everyone,

I’ve been dealing with random system slowdowns and the occasional BSOD on my Windows 11 PC for a few weeks now. After some research, I came across the method of a Clean Boot to isolate conflicts caused by third-party drivers or startup programs. But I’m not entirely sure if I’m doing it correctly and I’d appreciate some guidance.

According to what I’ve read, the steps are:

  • Open System Configuration by typing
    Code:
    msconfig
    in Run (Win + R)
  • Go to the Services tab, check „Alle Microsoft-Dienste ausblenden“, then click Alle deaktivieren
  • Open Task Manager, go to Startup and disable all entries
  • Reboot – this should start Windows in a minimal state

After that, you’re supposed to gradually re-enable services/apps until the problem returns, to pinpoint the culprit. Is that the right approach? I’m a bit worried about disabling something important – will hiding the Microsoft services really protect the essential ones?

Also, if I don’t encounter the issue during the clean boot, does that 100% mean a third-party software is causing it, or could it be a driver issue that stays active even with services disabled? Any tips on how to re-enable things efficiently (e.g., groups of services at once) would be great.

Thanks in advance for any help! I really want to avoid a full reinstall if possible.

Note: I’m on Windows 11 22H2, fully updated.
