I found this one accidentally by stumbling around in the registry looking for something else. Code: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization] "NoLockScreen"=dword:00000001 This is the reg key created by enabling "GPEDIT.msc/Administrative Templates/Control Panel/Personalization/Do not display the lock screen" which differs from the old one that works for W8. Oops...I meant to put this in the "findings" sticky. Would a moderator please move it there? Tnx.
