Pretty much the topic. I don't have this problem from the main admin account but it isn't a UAC issue. I've done all of the take control/give admin privileges/all other UAC stuff. It basically causes every program I try to start to crash immediately because they are unable to access any of the files they require to run properly. I've done about a billion different types of malware scans. I did an sfc scan from the prompt and the only issue was the iassdo.dll.mui which I was able to fix but the problem persisted. I think (but am very unsure) that I'm encountering some kind of corruption issue but I can't identify it. I created a new admin account and it has the same issue even though the main account doesn't. Oh, also I am unable to manage the account settings for the affected accounts. Just nothing happens when I try, nothing opens. Don't know if it will help but specs are MSI A55M-E33 motherboard, AMD A10-5800k APU, AMD R7 200 Radeon. Any help would be greatly appreciated!
