If you have XP a website you must have bookmarked!
So today I woke up, turned my computer on and noticed how the startups weren't running. I then proceded to open up Norton Antivirus to see if I had a virus in my system. However, Norton wouldn't run, it was asking what program to associate an .exe with. I then tried several other programs, all resulting in the same problem.
After feeling depressed for several hours and fearing I would have to reinstall Windows XP, I decided to just try a Google search. Surely enough, it came up with just what I wanted. Here is the site: http://www.dougknox.com/xp/file_assoc.htm . I hope this helps!
On a network of computers I wanted to (really badly) install firefox. I then changed .exes to open with paint, figuring, heck it's worth a try. Every time i loaded my account about 5 messages saying paint cannot open such and such file. I then got the IT admin to fix it, i even told her the problem, in such a way it seemed it was their fault and not mine...she ended up spending about 1/2 hour on it rather than taking my advise, as she thought
