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?

 

DNS problems with router

A couple suggestions I have for you:

Update the firmware on the router. Maybe it's getting into a badstate, and a firmware update might fix it. Or if you're comfortable with it, install a custom firmware like dd-wrt. Just make sure its supported on your router first.

Change your DNS to: 8.8.8.8, 4.2.2.1. Might help.

If none of these work, maybe statically set your DNS on your PS3/PC to the IPs you listed, taking the router out of the lookup procedure.

Last option, is look for a new router.
