How to remove the Lock option from the Ctrl+Alt+Delete screen in WindowsBy Lawrence Abrams on October 19, 2012 | Last Updated: December 21, 2012 | Read 6,437 times.
If you do not want users on a computer to be able to have the Lock option when they enter the Ctrl+Alt+Delete keyboard combination, you can disable it via a policy in the Group Policy Editor or via a Registry key.
To access the Group Policy Editor in Windows Vista and Windows 7, click on the Start button and type in Group Policy. You should then see an option called Edit Group Policy. In Windows 8, you should type Group Policy in the Start Screen and then click on the Settings category. The option for Edit Group Policy should now appear.
Click on the Edit Group Policy option and the Group Policy editor will open. Under the Local Computer Policy, expand the tree to the following path:
When you see Ctrl+Alt+Del Options, left click on it to select it as shown in the image below.
In the right-hand pane you should now see a variety of settings. Double-click on the Remove Lock Computer setting and its properties screen will open.
Select the Enabled radio button and then click on the Apply button. Finally click on the OK button and close the Group Policy Editor. Windows 8 will no longer show the lock option when that user uses the Ctrl+Alt+Delete keyboard combination. If you want to enable this feature in the future, just go back to the same setting and change it to Not Configured.
If you are using Windows Home, Starter Edition, or Windows Premium, then you will not have access to the Group Policy Editor. Instead you will need to enable the setting through the Windows Registry. This setting can be enabled by creating the DisableLockWorkstation REG_DWORD value under the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System Registry key and setting it to 1.
If you do not feel comfortable editing the Registry, you can download this Registry file that will remove the lock option for you:
Just download the above Registry file and double-click on it. When it asks if you wish to merge the data, click on the Yes button.
If you want to enable the lock option again in the future you can download and run this Registry file:
