I haven't even signed in on onedrive.

I updated my laptop to Windows 10 v1903 a week ago. After that, the performance of my system slowly started to degrade, browsers would lag, video players would lag quite a lot, windows explorer is...

I tried Revo Uninstaller but it couldn't find Nox App Player, so I installed it again and used Revo to uninstall it but no results.

Yeah

Even after deleting the "C:\Program Files (x86)\Nox" folder, I got the same message at the next startup.

I deleted it, so I don't know.

The startup folder is empty.

So every time I turn my laptop on, I get this message:
