Because people had been trying to help me I thought I would let you know that when I got back from holiday I had the same problem after eventually updating to Service Pack 1 that it was saying I had over 150 updates but kept failing to install them.I decided to pay £55 to have it taken back to how it was when I bought it and he downloaded some items for me and did some links so my printer would work. It was worth it as I am sure I would have got myself in a mess trying to do it myself. The computer is now running faster and I have up-to-date browsers and updates seem OK at the moment. I managed to install my Microsoft 2000 and HotMetal. I did think of upgrading to Windows 10 but can't face probably having problems with programmes I like to use so I will wait a while and then decide whether to go down that route.
