I have a hp desktop that I bought a few years back. The hard drive\nsmoked. So, I got a new hard drive. However, I don't have a copy of\nwindow xp to reinstall the os. Although, I have the cd code of the\nsmoke xp os in the back of the desktop. Where can I get a fresh copy\nof an xp os? Can I use the cd code of my smoked xp to activate the\nnew xp os? Do I have to call microsoft to activate the new os?\n\nthanks.
