If you have a retail copy (you purchased it yourself) the yes it can be
installed on another PC. If, however, it is an OEM copy which was
pre-installed on the laptop when you purchased it, then No. The OEM copy
will be tied to the laptop and not transferrable. (It is different if you
purchased an OEM copy yourself from a store and installed it, then you would
be able to transfer, but OEM's supplied with the PC are not transferable.)
As for registering, I have never register a copy of Windows. Activate
windows, yes, but don't register there is no point; well unless you want
loads of emails about other suitable products.
So long as the copy of XP has been on your 'deceased' laptop for more than
120 days you should be able to activate over the internet. If it hasn't been
on the laptop for 120 days or more the you will need to telephone the
activation line.
