Hi, I have been looking for the answer for a week on the net. Maybe I'm not stating my problem correctly. Here goes, I purchased Vista home 5/07(XP pro came with my computer, HP media PC m717on). Vista crashed on me with the last service pack update(I had it on auto download for updates). I lost my key code, so I decieded who needs vista anyway and rebooted XP from my recovery disks. I am on my computer, but my computer thinks I'm a guest, therefore I can't add my printer, download anything from the net, etc. I am worried about my virus updates and would like to be able to have my computer back. I thought my XP recovery disks would put XP back in full. Please advise.
