When I start my pc, (Nobara 43) Memory is up to 70% usage. I dual boot, but use Windows like 5% of the time. I have a Swap partition (64gb), but it shows 0b usage. Is it safe to kill the windows process? Can anyone shed some light into whats going on? I was starting to think this is sketchy lol


This doesn’t really say much; this could be legitimate software thinking it crashed, or it could be malware trying to hide itself.
Try seeing if
sudo find / -type f -name windowstells you anything about where it’s installed. This command searches through/(all files) to find a file (-type f) that is namedwindows(the same as the process name).weird
Heavily leaning towards malware; normal software tends to name itself the same on disk and in ram, this seems to be it trying to hide itself.
Since there’s now nothing to go off of for how this got on your system, the best course of action is to back up your documents and reinstall your system fresh. To avoid malware in the future, stick to the built-in app store and system repositories where possible.
See my top-level comment, but WinBoat does seem to set the process name for its Windows VM to “windows”.
Now if WinBoat is not used here, I agree this might be malware.
