I've got a guy here at work who thinks he knows a lot about computers, but doesn't. His computer is routinely the most fucked up, and we've straight up replaced it more often than any other computer here. As a side note, we only have about 15 employees and tech support is not my job, but I'm the only one that knows shit about anything electronic so I get to fix shit. There are no disk images or shit like a real company with real tech support might have. Anyway, this guy is making noise about yet another new computer because his is slow and acting up. Granted, it truly is running like shit, taking upwards of 15 seconds to load an excel file that mine loads in 3, for example, but I'm certain it is because he constantly fucks with it because he thinks he's smart. Not to mention he has fucking iTunes on there that never even syncs with his phone properly, so I'm sure that's a giant clusterfuck.
Sorry, he riles me up something fierce. Anyway, since I told the boss that this guy is fucking up his computers himself, they aren't just spontaneously going bad unlike every other computer here, I'm being given a shot next month to "clean it up" and see if I can get it running smoother to prove to him that the machine itself is still just fine. Of course I'm going to uninstall almost everything that I didn't install myself when I gave him the computer, and I'm going to uninstall and reinstall stuff like Office, etc. But my question is, since I can't just re-image it or take it back to factory settings, what is the best way to go about this? Will deleting his user folder and everything associated with it and then recreating it help any, or is that just extra work I don't need to do? I've already run every virus scan under the sun, so either it's clean or the viruses are bleeding edge. I'll also do simple things like sfc /scannow, and I've got all the software that would need to be reinstalled except the operating system, I just don't have any way to really "reset" it that I'm aware of. Oh, Windows 7 Pro btw, so I don't think that one had the option to refresh to fresh Windows install, unless I'm mistaken. And no, I can't upgrade it to Windows 10 either.
I realize there are ways to completely reinstall Win 7 and then activate it, but one of the owners is a big stickler about all of that and if I do anything remotely grey area with it I'll eventually get in trouble for it, and this isn't worth it to me to risk it, so as I said, I'm basically stuck with the current install that it has on it. I just need to "fix" it. I've listed the ideas I have, but I'm sure there are better ways to go about this, given my restrictions, so any assistance would be greatly appreciated. Thanks in advance.
