How To Change Lock Screen Timeout in Windows 8.1

Since many of my friends have asked me about there problems related to
Lock Screen in Windows 8.1, such as:-
* Automatic lock after one minute of Windows 8.1 screen.
* How to change lock-screen timeout.
* They searched a lot for solution but many of the ways people told, their
options are not found on the individual machines.
* Etc etc....
Thus after finding out I am writing this article to try and help them, support our sponsors by allowing me show ads and give those ads a try by seeing their destinations.
Microsoft has extremely pathetic Help and Support. They have not provided with basic functions on the go, specially after a problem of this nature, which we have been noticing from the time of their previous OS-versions also.
You need to make a change in your registry to include an option in your Advanced power settings for each plan.

Code:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f ​-f776-4464-8c53-06167f40cc99\8EC4B3A5-6868-48c2-BE75-4F3044BE88A7]
"Attributes"=dword:00000002

Immediately after editing the registry, you will see a new option to adjust in the advanced power settings for your power plan.




OR

To adjust the Windows 8.1 lock screen timeout, you will need to open an Administrator command prompt and use powercfg.exe.

Example: Setting the lock screen to 10 minutes instead of the default of 1 minute. (600 seconds = 10 min.)

Run there two commands on your command prompt:-

Code:

powercfg.exe /SETACVALUEINDEX SCHEME_CURRENT SUB_VIDEO VIDEOCONLOCK 900

powercfg.exe /S SCHEME_CURRENT
