The system was built by a friend so I can try to get the disc off him.
Either that or buy a new one that hopefully matches my computer.
Don't know if it's really worth starting from scratch just to get Windows Updates working again?
But I guess it's leaving it unprotected from important security updates if it isn't functioning?
Sounds like a job for the next holidays.
Thanks again for all your help and the time you've spent on it.
It's very much appreciated.
