| Sorry is this has been gone over before, but I purchased and installed
| about 30 "corporate" versions of XP and now when I try to do an
| update, MS tells me that I can't/number invalid BUT that it's a
| corporate version that was probably used to install a large number...
| yadda, yadda, yadda in essence telling me I'm legit (I am) BUT not
| letting me update.

| Did I miss something along the way?
