Windows 10: Encountered an error when start gpedit.msc

When I start local group policy editor an error message pops up:Encountered an error while parsing.Unrecognized input signature.I have tried searching on the internet, but the result is noting. None of them that can solve my problem. So, How to solve this?

I can't set a slideshow in the Lock Screen and one of the Microsoft suggestions to use gpedit msc didn't work

I can't set up a slideshow for the lock screen. I can select a picture from the computer or I can select one of the Windows 10 standard pictures. If I select slideshow it doesn't change the PREVIEW and when the computer is inactive I get a black screen.

One of the suggestions made by Microsoft in response to this problem in another post was to run gpedit msc. I have tried this or gpedit.msc or gpedit and in all cases the message I get is gpedit or gpedit.msc or gpedit msc "is not recognised as an
internal or external command, operable program or batch file"

How do I fix the lock screen problem or invoke the local group policy editor?

 

Gpedit problem

I just repair installed win 10 32 1607. Some things were messed up but I've been able to correct most. However I saw a recent post on how to remove Cortana. https://www.tenforums.com/general-sup...e-cortana.html. One suggestion was to use gpedit. But when I started gpedit,msc I got the attached message
The program ran after I dismissed the message twice but did not display the needed choices. I took a shot at editing the referenced file but couldn't save it because it's in Windows directory and is protected. (I am the Administrator). How can I fix gpedit?
