Private,
Right now, your computer has a Volume Licensing edition of XP Pro installed (Line 8), and that installation was done with a now-blocked Volume Licensing Key (VLK) (Line 2). VLKs are blocked by Microsoft at the request of the original keyholder for such reasons as the key was lost, stolen, compromised, misused, or expired. Also, MS may have blocked the key if it notices a pattern of misuse, ie, more installations of XP using that key than authorized.
As a rule, VL editions of XP should not be sold to individual consumers. Businesses, schools and gov'ts normally use VL editions for flexibility in installing many computers. Also, Windows XP Volume Licenses are upgrade licenses only and can never be used as the original or base license for an installation of XP.
If you search the forum for the part of the VLK reported by the mgadiag utility, YXRKT-8TG6W-2B7Q8, you will see that almost four dozen other posters have submitted reports with that same blocked VLK.
This is why you were seeing the "software counterfeiting" messages on your computer, because the current installation of XP is an unauthorized installation.
The next step is to look on the computer or with the materials you received with the computer or with your retail purchase of Windows to see if you have a Certificate of Authenticity (COA). If you have one, tell us about the COA. Tell us:
1. What edition of Windows XP is it for, Home, Pro, or Media Center, or another version of Windows?
2. Does it read "OEM Software" or "OEM Product" in black lettering?
3. Or, does it have the computer manufacturer's name in black lettering?
4. DO NOT post the Product Key.
Not sure what to look for? See this page for reference: http://www.microsoft.com/resources/howtotell/en/coa.mspx
Please have a look at the counterfeit gallery here http://www.microsoft.com/resources/howtotell/en/counterfeit.mspx to see if the materials you purchased would qualify as hi-quality counterfeits. If deemed hi-quality counterfeits by Microsoft, MS will send you a complimentary genuine replacement. To submit a report and request for replacement, just click the WGA star in the Notification Area (aka system tray) and follow the prompts. The evaluation process is said to take about 30 days.
