If you know the machine you want to keep,right click on the icon for xp/mode on your task bar and open "manage virtual machines" than you can delete the ones you don't want.You must have created more than one when installing apps. or ? unless your running the xp/mode .exe every time you start XP/mode. And I haven't had any problems yet I use FireFox,Sandboxie paid version , windows update,Xmarks for FF bookmarks stays current with all my bookmarks, microsoft security essentials just to keep the O/S happy,so far no issues.Touch wood cheers
