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?
Found this was tied to this KB article. Turns out there was not enough space on the reserved partition. So, I expanded the partition with this tool to 350mb, restarted and applied the update. It worked after that.
