I have a computer with XP Pro that will slow down to a crawl after a few times of switching between users. There are 4 different users on this machine. Each user is logging off when done, fast user switching is disabled. I go to task manager and there are multiple, sometimes up to 10, explorer.exe running with different users listed after each. I've done a Norton's scan and a Malwarebytes scan and the machine came up clean. Is it possible that a program is keeping these open even when logging off?1 person needs an answerI do too
