I used Nlite and the "merged" files work fine as a "new" ISO image on a CD-RW. (The application was so easy to use - no complex command line instructions I can never master.)
CD ran ok and booted up fine and installed without any glitches onto a rebuilt PC. However, after the install I have had some (occasional) messages in a typical Windows dialogue box suggesting that Windows doesn’t recognise the file and gives a message that I should "reinstall" correct files from my "Windows XP Home Service Pack 2 CD.
Despite that the installation seems to work fine and so far seems stable. I even done subsequent updates from the Microsoft update site.
So why is Windows giving the messages when all the slipstreamed files were from valid Microsoft disks? Was it because the original Window SP1 was an OEM version?
So should I worry?
