Eventviewer eventid for lock and unlock

Question

What is the event id in Event Viewer for lock, unlock for a computer in Windows XP, Windows 7, Windows Vista and Windows Server 2008?

Answer 1

For Windows 10 the event ID for lock=4800 and unlock=4801.

As it says in the answer provided by Mario and User 00000, you will need to enable logging of lock and unlock events by using their method described above by running gpedit.msc and navigating to the branch they indicated:

Computer Configuration -> Windows Settings -> Security Settings -> Advanced Audit Policy Configuration -> System Audit Policies - Local Group Policy Object -> Logon/Logoff -> Audit Other Login/Logoff

Enable for both success and failure events.

After enabling logging of those events you can filter for Event ID 4800 and 4801 directly.

This method works for Windows 10 as I just used it to filter my security logs after locking and unlocking my computer.
