Trouble with xp recovery

I have a pc with 27 virus’s so I went in and removed the virus’s. Now I cant get windows to start up. I need to remove all the special Programs that are installed on the pc cause i dont have the cd program discs for the programs. Now all are registered to me but I need to remove the programs and transfer them to an other pc. So, my question is how do I do this? remember that I cant get windows to start up…It keeps rebooting on me before the welcome screen will appear.I have tried the XP start up disc and it just gives me the dos and I dont know DOS.

ANY SUGGESTIONS??
