text: how can i disable win key, alt+tab?   you can do it via registry edit,  got to start -> run -> type 'regedit' -> press enter ----> a new window will pop up ---> on the left frame, open this directory, hkey_current_user&#92;control panel&#92;desktop  -> keep 'desktop' selected on left frame, you will see some information on the main frame ---> find 'coolswitch' ---> double click on cool switch ---> change value to 0 --> restart the pc. to enable it again change the value to 1 and restart the pc. hope this helps, good luck.
