Hello Until a few months ago I was using Windows XP with the windows login screen. As there are two accounts on this computer, we often left one logged in while we used another - using fast user switching. Then one day the computer decided to use classic logon mode, and I can't change it back. I have tried changing the log on method in Windows control panel, it lets me select XP Logon mode no problem - but completely ignores this setting and continues to use classic logon. I've tried downloading registry fixes, changing registry settings, used 3rd party programs to change the logon screen, checked that the fast user switching service is enabled.. etc.. nothing seems to work. Unfortunately I don't have any system restore points I can use to fix it, so apart from completely reinstalling Windows, anyone have any ideas how to fix the logon screen so I can use fast user switching again? Thanks!
