Hi Baz,
You activate it just like you did the first time, provided this is a regular
retail version of WindowsXP. If the original installation is at least 120
days old, then you will likely be able to do it automatically right over the
'net. At worst, you would need to phone it in and the number will be right
there on the screen.
If yours is an OEM version, then you may not be able to reactivate and would
be required to purchase a new copy of WinXP. The OEM version was cheaper
because of this and other limitations. If your copy was preinstalled, then
it is also and OEM but the manufacturer should be replacing it with similar
hardware and reactivation will not be an issue.
