"Windows must be re-activated"!!!!

  muddypaws 09:02 10 Aug 2009

Win XP Home SP2
On boot up just now and before fully loaded I got this message:
'Since Windows was first activated on this computer, the hardware has significantly changed. Due to these changes Windows must be re-activated within three days'.
I haven't changed anything deliberately. And am fully up to date with Win updates. Apart from no SP3.

Then after booting a balloon in the tray says:
"This copy of Windows must be re-activated to be eligible for the full range of upgrades and product support".

Hovering over a green star in the tray brings up the options:
'Activate this copy.
Purchase a genuine license.
Change notification settings.'
The latter goes to a Win page saying it has not passed genuine validation.

I don't have a CD so what now??
Would it be because I am working from a clone of 'C'?
I can change to boot from C, but it is a bit out of date now, 6-8 weeks.
I changed priorities as I believd C drive was being a bit problematic.
As luck will have it I should be on a new XP machine within 3 days.
The PC is 6 years old and has never failed any routine validation checks.
I see I have a product key sticker on the case.
Presumably I can enter this, but would like advice before so doing and should I enter it on C or P ( the clone)?
Many thanks.

"Would it be because I am working from a clone of 'C'?"

It shouldn't be - because a clone is an identical copy in all respects.

And even if the clone drive is a different specification to the other drive, that isn't normally enough to trigger an activation request.

Call MS from the number on the activation page, explain what's happened, and they're usually very helpful.

Why don't you have a CD?

The PC was purchased from Watford Electronics in 2003 ( God rest their soul!)
It came with no Win CD which I don't think is unusual from threads I have read here over the years.
Regarding the sticker on the tower this is the original manufacturer's one.
About 4 years ago I had a new motherboard installed by a local firm also no longer with us!
Presumably they would have needed a fresh code for Windows which I don't have or would they have used the original?
Will contactt MS.

Sorry to create a fuss about nothing.
I took a chance and went through all the Activation procedure and all is now OK.
Why the hiccup--no idea.
Thanks for responding.
