I was able to re-activate Win 10 which was unbootable staying at the windows logo, same as you mentioned.
My machine is an AMD Athlon 64 x2 5600+ with Windows 10 Pro, Version 1709
I did the following:
1.
download the windows10.0-kb4073291-x86_898d588fa98a78fdb7f121f14b74f51df2a9416d.msu from Microsoft: https://www.catalog.update.microsoft.com/Search.aspx?q=windows%2010%201709%20cumulative%20update%20
2.
store the package onto the partition with the unbootable Win 10
3.
boot the machine into Windows 10 Repair Mode, Advanced Options, select Command Prompt
4.
execute the following:
Dism /Image:C:\ /Add-Package /PackagePath:<path to the package>\windows10.0-kb4073291-x86_898d588fa98a78fdb7f121f14b74f51df2a9416d.msu /norestart /scratchdir:C:\Temp
5.
reboot
Hope this helps
Cheers Blubi
