For 3 days, Xbox game bar was not working, with error code 0x800007422 or something like that, which is error code "Windows Update Agent is turned off". I did some research and then found a post that said that it is nothing to worry about, it is just a problem in Xbox game bar that is happening with everyone recently, and the problem came from Microsoft. Later, when Xbox game bar was working again, I needed E-Books (school reasons) so I tried to install an app, but the Microsoft Store gave me the same error code as Xbox game bar. I did some research (AGAIN) but got nothing. I knew it had something to do with updates, so I opened Settings>Updates and Security>Check for Updates, to get a "Something went wrong, try reopening settings later". AFTER EVEN MORE (useless) RESEARCH, guess my search bar hated me and wouldn't turn on anymore, so guess what? YES! MORE RESEARCH! To discover that it had something to do with Windows Search Service being disabled. I turned it on (but it still doesn't work so please IF possible also give me the solution to that), and then wondered if there was something such as Windows Update Service, and turns out there was such a thing (lucky guess maybe) and it was turned off. I try turning it on but it instantly turns off right after that. I tried being fast enough to enable it and then start the service, but then it disabled and stopped. aFteR mOAre rESeArcH I ended up here since I found nothing. PLEASE HELP ME!
Update: My computer found two trojan viruses, which I deleted, but I feel like there is another since a LOT of symptoms are showing, like increased CPU usage, limited access, and when I ran a full scan I got two notifications at the same time. One saying that no new threats were found and one saying that a threat was found. I performed an offline scan, but when my computer turned back on, I was about to check the results when I got a "Your IT administrator (or something like that) has blocked you from viewing this data." THE VIRUS IS MESSING WITH MY PERMISSIONS AND EATING UP SERVICES ONE BY ONE!
Update 2: I ended up performing a clean install of Windows. Backed up everything on USB stick AND OneDrive. It should work now. Still warning people I send emails to to scan the files (just in case) for the next week or so. John Dev, sorry for the waste of time.
