You use to get up to 7 reinstalls before having to call MS. But with the latest copies of XP non-OEMs you have to call MS everytime you reinstall.

At home I've never had to reinstall it (I have much better control of my systems) But It's interesting to note that after-market sales are limited to one install. At work I have done many reinstalls for both OEM and Enterprise installs. There I have never hit the limit. 7 is an awful lot of reinstalls, in fact over two and it seams to me that you have other problems besides ythe OS. Ghost is also probably a better idea for most people. Burn a Ghost Image at initial install and before and after each major change. After all it takes about twenty minuted to re-Ghost a PC and it saves a great deal of frustration.
