Windows Xp re-activation

  Simsy 21:28 16 Feb 08


Due to a major PC malfunction I'm about to do, (another) fresh install of WIndows XP.

However, I'm also expecting to receive, in the next week or so, a different, faster CPU and more memory.

They will fit onto the existing mobo and there will be no other changes.

Am I right in thinking that if I do my fresh install and activate it, replacing the CPU wont require reactivation?

Thanks in anticipation,

Hi, a bit border-line I think, perhaps you had better contact Microsoft at Reading in Berkshire, I believe you will find them very helpful ......

No help available on that number at the moment.

Anyone else know, for sure?

I believe that if you change the CPU on your mobo, then as far as Microsoft are concerned you have a new PC, and as such you will require a new version of your chosen OS. You'll probably find that if you install your current OS and then try to activate it you won't be able to.

Scroll down to 'How Product Activation Works' then 'What Happens If I Upgrade My Hardware?'.

Looks like I'll be OK...

For the benefit of others, below is from the link you provided. Many thanks.

What Happens If I Upgrade My Hardware?

When Windows Product Activation detects one, two, or three hardware changes, it accepts the changes and reactivates your system, just as if there had been no changes. So you can add more memory or a bigger hard drive to your computer, or replace the video card and go on with your life without any interference from Microsoft. But if you try to change too many components at the same time, or if you try to install an existing copy of Windows on a new computer after the old one was destroyed or stolen, the online activation system will reject your request. In most computers, it takes four or more changes before Windows refuses to activate. However, the Windows activation system will automatically accept major changes (four or more of the items that trigger reactivation) through the Internet up to four times a year.

I've had to reactivate several times, and for the last few have been directed to the Helpline.

It takes only marginally longer than doing it on-line (unless you take down the re-activation code wrong!).

and I did a fresh install with the new CPU.
Activated online no problem.
Thanks for your interest.
