Windows 10: How To Fix MMC Error "detected error in snap in..." ?

I am trying to disable Cortana.

In the GPE I go to edit "Cortana" and I get a message that MMC has detected an error in a snap-in.

Found a fix on the web that involved adding to the system path.

But it hasn't worked.

Anyone got any ideas? hopefully.......

:)

 

MMC - Could not create the Snap-in

Having Windows 10 Version 1703 64-based on a HP Laptop.

Tried to install gpedit.msc, but continuously have error message

'MMC could not create the snap-in'

with 'CLSID: {8FCOB734-A0E1-11D1-A7D3-0000F87571E3}'

Have tried trolling Google with all suggestions

1) sfc /scannow - with no issues found

2) https://www.google.co.uk/search?q=M...&ie=UTF-8&gws_rd=cr&ei=LtR9Wa3jAoifgAbtg5rIAw

3) Fix for MMC could not create snap-in for Group Policy Object editor at Multiplay Labs

4) Enable/Disable Group Policy in Windows Xp from cmd or Regedit

5) http://troubleshooter.xyz/wiki/fix-mmc-could-not-create-the-snap-in/

Where one suggests to delete the 'CLSID: {8FCOB734-A0E1-11D1-A7D3-0000F87571E3}' in the registry to create a new clsid on reboot/restart, I cannot delete it as it returns as an error.

Have installed the gpedit.msc on my Tablet with no issues with same gpedit download.

Any clues
