I've been running Wndows 10 for a while. When it tries to update to Windows 10 Pro, version 1511, 10586, I get the following in the event log:
Installation Failure: Windows failed to install the following update with error 0xC1900200: Upgrade to Windows 10 Pro, version 1511, 10586.
My research shows this error says something is incompatible so I can't upgrade, however I'm already running Windows 10.
Do you have any ideas?
