Just in case you find yourself converting some old images and you get a nasty little error like this:

Error Code: 0x80360051 While "inserting required drivers in the image"

Try this:

Regedit
Select Local Machine

Load Hive from within your problem RiPrep Image

E.G.
\\WDSSERVER\reminst\setup\English\Images\BrokenIMAGE\i386\Mirror1\UserData\WINDOWS\system32\config\system

Name it something

Find in Regedit under the loaded Hive:

HKEY_LOCAL_MACHINE\something\System\ControlSet001\Control\CriticalDeviceDatabase

Check every key to ensure that there is a ClassGuid for each, if there isn't then modify the security on the key and delete it.
(unless you want to figure out what the ClassGuid should be)

Unload hive

Go back and convert this image to wim.
