I have messed up and had to downgrade to Windows 7. I am currently trying to catch up with my updates, but keep heaving problems with Microsoft XML Core Service 4.0 updates. First, one I resolved by manually downloading it. Hopefully this one is going to be just as easy to fix.
I am was trying to reset Windows Update component and got “The module “mshtml.dll” was loaded but the entry-point DllRegisterServer was not found. Make sure that “mshtml.dll’ is a valid DLL or OCX file and then try again”.
