I installed XP Pro SP2 on a newly formatted C: drive on the same Dell Dimension 8100 computer that had been previously running XP Pro. It worked fine.
I went to Update.Microsoft.com and installed all the high priority fixes, including SP3, and most of the other updates.
Now, the computer reports that it is running XP home!
What happened? More importantly, how do I get back to XP Pro?
My installation disk is an original Dell OEM disk labeled "Microsoft Windows XP Professional".
[SMS Inventory Identification] Version=1.0
[Product Specification] Product=Windows XP Home Edition
Version=5.0 Localization=English ServicePackNumber=0 BitVersion=40 [Version] DriverVer=07/01/2001,5.1.2600.0
I looked for gpedit.msc and it does not exist. I also checked a backup I did after first installing XP pro and it did not exist there either.
Finally, I checked prodspec.ini from the same backup. It also says XP home.
So is it really possible that the original Dell OEM installation disk has the wrong version on it? (Can I look at any file on the CD itself to tell for sure?
