Windows 7: Service Pack won't install

17 Oct 2015   #1

Windows 4 Ultimate 64 bit
Service Pack won't install


Every time I start up my machine I get the following message from Windows (I'm using Windows 7 Ultimate 64 Bit):

Configuring Service Pack
0% complete
Do not turn off your computer

This remains completely unchanged for about 10 minutes then changes to:

Failure configuring Service Pack
Reverting changes

Does anyone know how I can fix this or stop it from happening?

Many thanks.

Can't (re)install Service Pack 1
I'm havin' a bit of trouble installing Service Pack 1. Either that or Windows Update wants to make an excuse and stop the installation halfway and then spit out a random error code. Failed - Error Code 8024200D Would downloading the MSU file help resolve what's halting the update process?
