The cut off date for PC makers to obtain licenses for the software was 31 January 2009.
But now Microsoft has put in place a scheme that will allow the hardware firms to get hold of XP licences until 30 May 2009.

Despite Microsoft's claims that Vista has sold well, consumers have reacted badly to its release.
