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) MMC could not create the snap-in - Google Suche

3) https://blog.multiplay.co.uk/2013/1...reate-snap-in-for-group-policy-object-editor/

4) http://computerstepbystep.com/group_policy_windows_xp.html

5) How To 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

 

Convert Windows Server 2012 R2 Evaluation to Windows Server 2012 R2

I have purchased the product key of Windows Server 2012 R2. Now the server is on Windows Server 2012 R2 Evaluation. I found a few links there they explained on how to convert from Windows Server 2012 R2 Evaluation to Windows Server 2012 R2 with valid product
key. One of the example is this link:

How to activate Windows Server 2012 R2 Evaluation - Nicolas Ignoto, CTP

Is this a correct way to do? If I follow this step, will my data be erased?

I want to avoid formatting/fresh Windows install because there are some software in the server that we do not know how to backup. We just want to get it activated now, backup will be sorted out later.
