Resolved Down loading Licenced OS to new HD

Hi, My sister inlaw has a licenced copy of Windows XP on her Desktop PC, which the HD has died on, it did not come with a disc,
Can she download a new Windows XP OS to the new drive using her licence number,
She rang the E machine maker and they told her she can only get a 60 trial ????
I thought that once I bought the OS I was entitled to a copy for ever.
Any suggestions
Thanks Des.

 

Thanks Steve, I have a XP Pro disc , so I will look around for a XP Home Disc , you think that the shop would know that, I think they are trying to make it hard for a woman???
Thanks again
Cheers Des.

 

Hi, Thanks again for your help. I will mark this resolved as she is buying a whole new setup. Cheers Des.
