I was looking at my computer in depth today and I found that I have got a file in there which has a name consisting of loads of numbers and letters, all mixed up. When I enter the file, I see a setup icon with "Windows XP sevice pack 1" next to it, and 3 files:
Where did this come from...I prsume it's a Windows Update thing. The thing is, when I go into the "My computer" properties, it says that I have Windows XP SP1.
I think it is from when service pack 1 was installed as it gives you the option to backup the files it will replace so if it went bad after the install you would be able to uninstall it, I may be wrong but thats what it may be. Have a look in add/remove to see if there is an option to uninstall service pack 1
