when i start my computer instead of the normal welcome screen coming up the classic mode type login comes up (similiar to windows 2000). I tried to change it by going to the control panel selecting user accounts and selecting change the way users logon and logoff. when i do this a message saying "Class factory cannot supply requested class." comes up, and I cant change my settings. How do u get past this error.

some programs will alter login setting when installed, usually programs with login settings of their own. ie: VPN, etc.

only fix is to uninstall the program. i think.

thats not what i asked. The problem is not with a program, it is with startup. It is with the control panel settings and not allowing me to change them

What about a system restore back to the days before the change .

i tried but there was no restore date in that same month
