Apparently, many legitimate Windows users are none-too-pleased with the latest update to Microsoft’s license validation software, Windows Genuine Advantage. If your computer keeps telling you that it has an invalid license, try this: Open Internet Explorer and go to update.microsoft.com. Download the latest version of Windows Genuine Advantage, if prompted to. Restart Windows if asked. Open Internet Explorer and go to Tools > Manage Add-ons. Select Add-ons that have been used by Internet Explorer from the drop-down menu. Find the Windows Genuine Advantage entry, highlight it, and click the Disable button at the bottom. Click OK to save the new settings and exit. While this should circumvent the WGA software, you might want to contact your computer manufacturer to find out why your license isn’t valid.
