Steve314 http://goboef.nl/?id=users/31438 2014-01-27T17:57:29Z 2015-08-12T14:57:20Z <p>I bought a new motherboard last week. Windows 7 is running well, so now it's time to get my Windows XP running.</p> <p>I can't install direct from the original Windows XP Home CD (retail version) because it crashes, possibly because it's only SP1, also because of problems with AHCI. So I made a slipstream Windows XP disk using <a href="http://www.nliteos.com/download.html" rel="nofollow noreferrer">nlite</a> version (most recent version - I've checked now).</p> <p>The basis of the slipstream disk is the Windows XP Home SP1 retail disk. The only changes I applied using nlite were to change it to SP3 and to include the AHCI/RAID drivers for the motherboard. This resolved the crashing issues, and the install now progresses as far as entering the product key. But it rejects the product key, saying it's not valid.</p> <p>Motherboard is an Asus M5A97 Evo R2.0, and the AHCI/RAID driver was on the CD (though the easiest way to find it was to create a RAID driver "floppy disk" using an IMDISK virtual drive - the hassles of using legacy stuff on modern machines).</p> <p>Note - this is based on an original Windows XP Home <em>retail</em> CD, and using the valid Windows XP Home <em>retail</em> product key supplied with that CD. The key is valid, I have re-entered several times, and I have double-checked with the yellow "sticker" on the original cardboard folder with the documentation. I've installed from the original CD many times before without problem, and I'm sure this isn't the first time I've made a slipstream disk from it. And I'm definitely using a retail XP home product key with what should be a retail XP home slipstream disk.</p> <p>In case nlite had somehow converted a retail CD into an OEM cd, though, I also checked with two valid Windows XP Home OEM licenses - and they were both rejected too.</p> <p>Finally, this is during the installation of Windows XP. The machine has all network connectivity turned off. Even if I've upset Microsoft by using this XP license on too many different PCs over the years, the installer should have no way of contacting Microsoft to know that - that should be a problem for activation, not for the initial entry of the product key during installation.</p> <p>So - can anyone suggest a reason why Windows XP would reject a valid product key and what I might try to resolve the problem?</p> <p><strong>Update</strong></p> <p>I've made a slipstream CD from an OEM Windows XP Home SP2 disk, with SP3 and the AHCI/RAID drivers integrated as before, and using a valid OEM product key. That worked fine. I have backup disk images so I don't need to go through all this again next time.</p> <p>I'm still curious, so I may experiment with a slipstream of the retail disk with AHCI/RAID but left as SP1, or integrating SP2 rather than SP3. I haven't found a way to check whether my product key has been blacklisted, but I'll try that again too.</p> <p>I won't be finished with this for probably a few days.</p> http://goboef.nl/?id=questions/707771/-/707777#707777 2 Answer by RobLaw0304 for What can cause Windows XP to reject a valid product key?

I've always been under the impression that the new service pack came with an updated blacklisted key database built right in. Unfortunately for you, this seems to be what may have happened.</p> http://goboef.nl/?id=questions/707771/-/707794#707794 2 Answer by Scott Chamberlain for What can cause Windows XP to reject a valid product key? Scott Chamberlain http://goboef.nl/?id=users/25625 2014-01-27T18:45:07Z 2014-01-27T18:51:17Z <p>I think Windows changed it's CD key algorithom between RTM and the SP's. </p> <p>I don't know when it happened or if it happened more than once, however I think the act of slipstreaming SP3 on to the CD may be changing the key check algorithm and that is why it is failing.</p> <p>The only reference I could find to back this up was was from <a href="http://winsupersite.com/article/windows-xp2/slipstreaming-windows-xp-with-service-pack-3-sp3-128464" rel="nofollow noreferrer">this guide</a> for slipstreaming SP3 on to a SP2 CD:</p> <blockquote> <p><strong>Step 6: Test, install it properly, add updates</strong></p> <p>...</p> <p>Do not enter your product key during Setup: I've heard from readers and have read separately online that there is a problem in some cases where Setup will not accept a valid Windows XP Product Key on an integrated XP with SP3 install. For this reason, you should choose not to enter the Product Key until after XP is installed. Obviously, I can't test every possible permutation, but I have successful activated XP integrated with SP3 on my own systems repeatedly in this fashion.</p> </blockquote> http://goboef.nl/?id=questions/707771/-/707877#707877 0 Answer by joeqwerty for What can cause Windows XP to reject a valid product key? joeqwerty http://goboef.nl/?id=users/10618 2014-01-27T21:54:19Z 2014-01-27T21:54:19Z <p>Create a slipstreamed installation CD/DVD from the original CD WITHOUT slipstreaming SP3 into it. Then try again. If it works then you'll know that SP3 being slipstreamed into the installation is the problem. You can download and install SP3 after the initial install is completed.</p> http://goboef.nl/?id=questions/707771/-/956004#956004 1 Answer by Steve Schulz for What can cause Windows XP to reject a valid product key?

You have to be running XP to perform the slipstream. <a href="https://support.microsoft.com/en-us/kb/950722" rel="nofollow noreferrer">https://support.microsoft.com/en-us/kb/950722</a></p>
