Making an older computer new Options

[Maccabee]

I am currently on a desktop running xp(my favorite os) and it used to be somebody elses and I had a few questions.

1. How can I remove programs properly without leaving regisrty files and junk which eventually slow it down.

2. How can I change the full computer name.

It was music box but i changed it to CohenComputer. But music box keeps coming up all over the place. More about that will be explained in a minute.

3. When I go to documents it doesnt show the My videos My music and My pictures buttons.
When open the folder ARCHIVE_THIS_PC I see them with their little icons. I tried to just copy and paste them to my documents which worked but then whne I open the start menu the shortcuts to the right changed from My Music and My Pictures to Cohen's Music and Cohen's Pictures and I cant click them! ANd when I right click them and click properties it says the location is blahblah\Music Box\documents\Archive this pc\my pictures or whatever. Weird I know!

So if I oculd have resolutions for those that would be great or if I could find a way to pretty much reset my computer or format it but keep the os. Cause I dont have an xp disc.

the next time you restart the computer, press & hold key F11 when it's starting up. that should go to whatever recovery program you have on the computer. if nothing happens, you might not have it and would need startup disks and/or the OS cd. however, even if you do manage to access the recovery program, it might still require startup disks. maybe you'd like to ask the former owner of the computer if he has any of these disks.

i haven't presonally used ccleaner, but i know some people who do. i've used system mechanic before, and i was happy with it. i don't know if it really matters what registry cleaner you use. you should look through other forums though, to avoid deletion of files you might actually need.
