Hi folks....Im new to posting on here but I have been reading alot of posts on here lately and thought I'd ask a question myself. ..I cant seem to find a straight answer to the problem Im having and I know alot of others are having it too...Heres the problem.. I am trying to create an unattended Installation CD From a Dell OEM Windows XP Home Disk. I have a Dell Dimension 8200 Home computer. It came with a set of Setup CD's. The one CD is Red and says "Operating System Windows XP Home Edition"... Now im going to assume this is what is called an OEM Windows XP CD... I have slipstreamed it with SP2 and integrated all the hotfixes and burned a new CD. It works fine..installs correctly and needs No activation. But as soon as I start editing the WINNT.SIF file things go wrong. It installs fine....Installs my drivers, Wallpapers,Screen Savers..ect but it wont activate. I have tried averything I could find to make it work but it still wants me to call M$. I have tried the WINNT.SIF Method, The Backup Method and the OEMBIOS Method. It seems that the OEM Disk doesnt Use the WINNT.SIF file. There is one on the disk but it says that it is just a sample and when I replace it with a working file then Windows wont activate unless I call. Now this isnt something that I really NEED or anything. But Im one of those people who like to try to get things to work and this is driving me nuts. I went to this site as someone sugguested but it doesnt give a key for XP Home http://www.microsoft.com/technet/prodtechn...y/oempreac.mspx I appreciate any help Thanks, Andy
