Compaq customers are furious that their promised upgrade to Windows XP may be delayed for up to six weeks.
Customers who recently bought Compaq Presarios with Windows Millennium Edition have told vnunet.com that they are unable to register to receive their XP upgrade at the specified area of Compaq's website.
As of 29 October the registration area is taking emails to add to Compaq's files, but is giving no indication to customers when they will receive their promised upgrade.
They are simply sent an automated email saying: "Microsoft plans to make Windows XP available on 25 October. We will mail you again approximately two weeks before the program is available, at which time you will be able to order your copy in advance."
Andrew Cleland, who bought a Compaq Presario 5146EA from PC World earlier this month, said that Compaq's customer support had told him he would have to wait up to four weeks after he had registered, making a minimum wait of six weeks.
He told vnunet.com: "I'm pretty miffed. The whole idea of buying a PC before XP came out seemed like a strange idea, but rather than wait I fell for the sales pitch when they promised that the free upgrade would be easy. They're neglecting the people who bought early. I wish I'd kept with my gut feeling and waited until XP came out."
Compaq said they were unaware of the problem and declined to comment at time of publication. However, the registration area of the website had still not been updated by 0915 GMT on 30 October. The firm was unable to explain why this was so at time of publication.
