I cannot seem to update, and using the Windows 10 Update Assistant reports that Windows is installed in an unsupported directory, and it cannot proceed to update without clearing all of my data (PC specs are below).

I tried clearing the Windows update cache, and it redownloaded through Windows update, and it rebooted, and got to 18% and then rebooted, and then got to the boot screen and said Updating your system, and at 5% it said FATAL ERROR and an error code. This happens every once in a while now, when it attempts to update.

I tried all troubleshooters, everything, even using an MSU file to update, and using the installation media to update, but nothing worked.

I use UltraUXThemePatcher for my UX theme, as I use a custom dark theme, and I have some registry tweaks like no lock screen, dark Alt Tab backgrounds. I use Listary for search. I have a registry tweak to set default program files folders to my D: drive.

I am on Windows 10 1803, 1809 refuses to install, and I don't have a dedicated DVD/ROM drive.

I will be happy to respond in this forum.

I was kind of waiting for this question.

While the Bluetooth adaptor is one thing that does this, the windows update process checks for certain things then fails if they are not there. This is stored in registry (boo!) and the tool that reads it was a little hard to find.

MS has a tool for advanced users called SetupDiag that looks through the logs and tells you precisely why newer versions of windows isn't running a feature update. In my case it was backup software (macrium) that had changed a registry entry (related to volume shadow copies) and didn't reset it once uninstalled . It also tells you what to do.

Unlike the update troubleshooter, it dosen't run through a series of useless steps - it tells you what's wrong, and expects you to fix it. Which is much better.
