Unfortunately, many people who do have legitimate copies of Windows are unable to validate their computers through WGA. This is frustrating, since the validation process is a bit of a black box, especially for people who aren't technically inclined. But even those who are technically inclined may have a hard time diagnosing why WGA isn't working.
Microsoft has created a tool to help disentangle WGA validation issues. The
The program has four tabs: Windows, OEM, Office and Browser. Each one lists diagnostic information that can be used to determine a problem with WGA.
The main Windows tab will list whether or not WGA has validated Windows as genuine in the first place, as well as product ID and WGA version information (to determine, for instance, if there's an earlier version of the WGA components installed).
Under Browser, you can examine a number of common browser settings that can cause WGA to fail if they aren't set correctly. Note: One important setting -- whether or not data sources can be access across domains -- is notlisted here. This is because it is not a browser-wide setting but a zone-specific setting, and so needs to be checked depending on what zone you have Microsoft.com set in for your copy of IE.
The tool can be further used in conjunction with Microsoft's own interactive WGA diagnostic Web site.
