Rudy Mas Take a look here and give this a try. Might fix it right up...
Uanble to install Windows Updates, Error code 0x80073712 - Microsoft Community
Mine downloaded and installed all ok tried everything all good so far
So, I decided to just go the easiest way, instead of trying to find why it didn't work. I mounted the 1607 ISO and ran the setup. After the installation, my Win10 version is at 105.
I uninstalled Visual Studio 2015 a couple of weeks ago and also all the other stuff connected to VS2015. By doing this, I probably uninstalled something which Windows 10 needed to make Windows Update work.
So, by doing a fresh installation, it should have fixed it all. I will know for sure when the next updates will arrive.
My system was plagued by boot-up, freezing, and other strange issues after the Anniversary update. The latest update fixed all those issues and the system is now super stable again.
I read recently that this is a known problem involving machines that had an SSD for the C: drive and with personal files (Documents, Pictures etc.) on a separate drive (in my case a 2 TB internal rotational drive). (My programs are also on the SSD). I was hoping that the above KB would solve it, but no luck.
Am I now stuck with this bug?
Would be nice if you have a tag similar to INSIDER, XBOX and INSIDER. Maybe call it WINDOWS REG for everyone else that doesn't have INSIDER.
