Can't Upgrade to Windows 10

HP Recommended
HP Pavilion Slimline 400-200 Desktop PC series
Microsoft Windows 8.1 (64-bit)

I have tried to run the Windows 10 Installer to upgrade my PC from Windows 8 to Windows 10. Every time I get the error that the Windows 10 Installation has failed. I ran the Windows Update Troubleshooter and it reports that something gets fixed every single time. So I thought that maybe I need to run it until there is nothing left to be fixed. That point never came. Then I got the report that the service registration was missing or corrupt and that it wasn't fixed. I don't know what to do to fix it. 

I downloaded the installer on the DVD and tried to start BIOS from DVD installer and that didn't work either.

If you're trying to do the Win10 update using Windows Update and that is failing, then look into the Windows Update history because for each failure, it provides an error code.


You can then go online using those codes and get hints on how to address each of them.


You said you tried the update from a DVD, but we need to know the following:

1) HOW did you download the installer onto the DVD -- asking because the Win10 installer is typically to big to fit onto a DVD

2) Did you try to boot from the DVD? If so, you need to tell us the details of the failure not just that it didn't work.
