Blocking Windows Hotkeys!!!!!It is possible to prevent users from using the Windows shortcut hotkeys - like Alt+Tab and others - by simply following steps given below:-
1) Start > Run > "regedit" (without the quotes of course)
2) Search for, or create the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\Windows\CurrentVersion\Policies\Explorer
3) Create a new DWORD value (within the above registry key) called "NoWinKeys" and set its value to 1 to disable all Windows hotkeys and 0 to enable them.
4) Exit the Windows registry and restart the Windows session for the change to be applied.
