If you are running the preview version of Windows 10, you may be aware that an updated version is available and should be installed through the Update and Recovery section from the PC Settings in the Charm bar.

Ok, but if you have enabled Media Center this operation will failed with the error code 0x800700EA. I found that is the Media Center feature which cause that issue thanks to the Windows community forum (only place I found exact same issue BUT with no solution except reinstalling without enabling Media Center – as reminder this come with an specific product key).

So as I did not want to reinstall it (even by doing an inplace upgrade), I dug a little and found 2 registry keys have to be updated to allow me getting the updated version of Windows 10.

You have to change the value of the following keys:

  • EditionID, change from ProfessionalWMC to Professional
  • ProductName change from Windows 8.1 Pro with Media Center to Windows 8.1 Pro

These keys are located below HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion and HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion.

After changing the value of these key, restart the client and go to the Update and Recovery section to get the updated version.
