• By press ctrl+alt+del and select the process tab. Find WgaTray.exe in the list. To make it easier to find it, you can sort the list in alphabetical order by clicking the Process title at the top. Highlight WgaTray.exe.

Microsoft hopes that by notifying users that they are not eligible for all security upgrades it will drive more users to purchase a legal copy of Windows, and also report the counterfeit dealers that sold them their copy. In some cases Microsoft will give a free license to users who are victims of a high quality counterfeiting.

However there are good news for those who still don’t wish to validate their copy (and no it is not GEICO). There is a way for users to turn off the notifier but it may be turned back on in the future as they try to download the latest updates to IE or Media player or take advantage of the Buy Local offers through their local system builder.

And last note, if you think that this is the end, Microsoft is preparing enhanced notification and better validations in Windows Vista.
