Seems to run everything in the Microsoft Store (the preinstalled Windows 10 games, despite having opened one ever, are in the Task Manager, seemingly the reason why the C drive is capped and then goes down). When installing something, a popup asks "You need to install an app for this task. Would you like to search one in the Store?" This cannot be closed or moved. And I think I can't manage the startup programs in regedit, as well as I cannot delete processes in Task Manager (Internet Explorer has been running in the background, waiting to be killed). Cortana and Microsoft Store has been using the most network time... Chrome had a "your connection is not private" error a half hour back...
AdwCleaner detects pup.optional.legacy but that's it for the detected files, even checked Avast and didn't find anything.
Funny, I wanted to do this for checkups today but it seems like I have a virus myself .-.
I'll update for any of the Weird ***** that happens:
added microsoft edge to the "do not disturb" list in avast, which silences notifications from everything. it does this to games, but to do this with programs is ominous.
