what is your computer doing
i may be new to somethings but windows xp and 98 are my specialty. is your computer just slow, has trouble getting on the internet, error messages, etc. i can help you fix it with just knowing what the symptoms are. microsoft does offer a free complete download of windows xp operating system or boot disk on their website but it wont be found my a basic search. most generally it is just minor clean up that needs to be done. generally your registry rarely has to be cleaned. if necessary i have a few programs that are free and highly recommended by my brother who works for microsoft as a software programmer.
