This week I held a class at LabCenter and I get a question:

I would like to block the Windows 8.1 Update from windows store, how do I do?

The answer is:

Open Regedit and set HKLM\Software\Policies\Microsoft\WindowsStore to one.

You can also do it using Group Policy by going to Computer\Administrative Templates\Windows Components\Store enable turn off Offer to update to the latest version of Windows

Thats All
