I'm running a fairly high end computer at around 30% load. For some reason, task manager is very slow. I'm getting black artifacts, the tabs aren't always loading and sometimes it just freezes. Everything else seems to work just fine. For some reason, it's running with normal priority, rather than above normal, and I cannot change it. Maybe this changed with Windows 10?
What can I do about this, other than reinstalling Windows? Is it enough to suspect something messing with task manager, like a rootkit trying to stay hidden?
EDIT: apparently I have a few thousand
conhost running with no parent process. Smallest processid is 224, which is before login. There are also 470k handles open. This will require some digging.
