First of all uninstallers, registry cleaners and system cleaners will not remove applied tweaks, they will have to be removed by scripts or registry editing.
Uninstalling Tweaking.com - Advanced System Tweaker will not remove the applied tweaks.
First try Tweaking.com Online Help- http://www.tweaking.com/articles/pages/tweaking_com_advanced_system_tweaker_online_help.html
If you can't find the solution then try posting a topic in the support forums- http://www.tweaking.com/forums/index.php/board,2.0.html
Also try to
download and install the most current version from the developer site, since many download sites don't have the most current version with bug fixes.
I do not see any tweaks for "SWITCH BETWEEN WINDOWS" IN MY COMPUTER on the program. Could you provide a screenshot to show this tweak?
Also Advanced System Tweaker has Backup and Restore registry which can undo any of the tweaks which is recommended to Backup Registry each time you use the program. Registry backups are located by default- "C:\Reg_Backup".
Good Luck.
