How to Disable 'Lock This Computer' in Vista Premium

The lock option also appears in the Start menu.

Windows Vista Home Premium and other editions of Windows have a Lock This Computer option users can access from the menu that appears when they press "Ctrl," "Alt" and "Delete" simultaneously. When a computer is locked, it can't be used until the user types in her password again or a new user logs in. This option is normally disabled using the group policy editor for system administrators, but it isn't available in home editions of Windows Vista. Adjust this setting in the Windows registry editor.

Instructions

1. Click "Start," type "Regedit" into the Start menu's search box and press "Enter."

2. Click "Continue" to the User Account Control prompt that appears.

3. Navigate to the "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\" key in the left pane.

4. Right-click the "Policies" key, point to "New" and select "Key."

5. Type "System" and press "Enter."

6. Right-click the "System" key, point to "New" and select "DWORD Value."

7. Type "DisableLockWorkstation" and press "Enter."

8. Double-click the "DisableLockWorkstation" value in the right pane.

9. Type "1" into the value data box, and click "OK."
