Apple was quick to post a fix for iTunes 8 issue that caused Windows Vista users to see the BSOD (Blue Screen Of Death) when plugin an iPod Touch or iPhone.
From Apple:
After installing iTunes 8 for Windows, some users may see a blue screen error message when connecting iPhone or iPod to a Windows Vista computer.
The fix involves uninstalling Apple Mobile Device Support then reinstalling the updated iTunes 8 package. One of my previous posts involved uninstalling Apple Mobile Device Support then reinstalling iTunes 7.7.
