How to remove Media Center from Windows 8

Set-Edition is not supported with /online - only usable on offline images

On my system, there is no sign of a restore point (surprising) but it is only a short while since I did the addition (earlier today) and I certainly haven't removed any restore points/cleaned up.

So I don't think the above answer works.

Here is what worked for me:

1. Edit Registry
2. Run setup file

Or as you can see in this tutorial:

1. Go to your Windows Registry and locate : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
2. Change EditionID(Professional) and ProductName(Windows 8 Pro) values
3. Close Registry, Restart Computer
4. Download the Windows 8 Setup.exe file from the following link.
5. Enter your valid Windows 8 Professional key that you purchased from Microsoft.
6. Run the install and choose to keep all existing apps and settings.
