How to change Windows 10 Lock Screen Timeout Period

Windows 10 has a beautiful "Windows Spotlight" background on the lock screen.

The problem is that by default you only get a minute of it. Here is how to set that value.

Open Registry Editor and navigate to the following key: 

HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Control\ Power\ PowerSettings\ 7516b95f-f776-4464-8c53-06167f40cc99\ 8EC4B3A5-6868-48c2-BE75-4F3044BE88A7 

Now in the right pane, you will see Attributes. Double-click on it to change its DWORD value data from the default 1 to 2.

Having done this, now open Power Options > Advanced Power Settings via Control Panel. Expand the Display item. You will now see an additional entry: Console lock display off timeout. 

You would not have seen it earlier, but after editing the registry, you will get to see it.
