User · Answer

Using Windows 10 Home edition   I was unable to get my event viewer to capture events 4800 and 4801  even after installing the Windows Group Policy Editor  enabling auditing on all the relevant events  and restarting the computer   However  I was able to discover other events that are tied to locking and unlocking that you can use as accurate and reliable indicators of when the PC was locked   See configurations below - the first is for PC Locked  the event connected to displaying C  Windows System32 LogonUI exe  - and the second is for PC Unlocked  the event for successful logon

The lock event ID is 4800  and the unlock is 4801  You can find them in the Security logs  You probably have to activate their auditing using Local Security Policy  secpol msc  Local Security Settings in Windows XP  -  Local Policies -  Audit Policy  For Windows 10 see the picture below   Look in Description of security events in Windows 7 and in Windows Server 2008 R2 under Subcategory  Other Logon Logoff Events

To identify unlock screen I believe that you can use ID 4624  But then you also need to look at the Logon Type which in this case is 7  http   www ultimatewindowssecurity com securitylog encyclopedia event aspx eventid 4624  Event ID for Logoff is 4634

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
