Troubleshooting dumb sysprep errors
Your sysprep might bomb out and tell you to review C:\windows\system32\sysprep\panther\setuperr.log. Inside that file, look and see if you have some error similar to:
SYSPRP Package Microsoft.BingSearch_1.0.blah.blah...
Take note of the EXACT package name.
Remove-AppxPackage -Package FULL-PACKAGE-name
Then try sysprep again.
