As everybody knows, using the Windows+L keys together will lock your workstation running XP or Vista. Did you realize that you can also disable this function by using a registry hack?
I suspect that this article will be much more useful to those of you who can't lock your workstation, but either way we'll show how to configure this setting.
Manual Registry Hack
Open Regedit.exe
Now Navigate To
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
On the right-hand side, create a new DWORD 32-bit value named DisableLockWorkstation and give it one of these values:
1 - Disable Lock Workstation
0 - Enable Lock Workstation
The changes should be immediate, no need to restart anything.
nice trick friend!!
thanx for sharing it..
