I've been running XP with two users quite happily for a number of years.
A couple of days ago I downloaded AVG's antivirus 2012 update and took advantage of the free PC Tuneup - now I can't switch users. I have certainly tidied my PC up a lot but I don't know what setting I changed but now I can't switch but need to log off. I've done the standard thing of control panel then user accounts and change the way users log on or off. I set the Use fast user switching flag and apply options but this doesn't seem to take. If I look again, the option is unset.
Can anyone help? It's very frustrating having to close all my programmes and log off just for my wife to check her emails!

Windows system restore prior to your "tidying up"
 

You are welcome !

PS: If you need to "tidy up", suggest simply using the Windows disk cleanup.
Those 3rd party tuneup packages use a registry cleaner, and it is not really desirable to run those things !
