The problem appears to relate to a malformed Registry Key.
It may (or may not) be reparable by use of the CheckSUR tool -
Please download and save the CheckSUR tool from http://support.microsoft.com/kb/947821
(you'll need to look in the details for Windows 7, downloading from the Microsoft Download Center)
Run it - The tool can take anywhere from 5 mins to a couple of hours to run (or 'Install') depending on how much it has to do, and may exit silently - it may appear to freeze for most of that time, but be patient.
The result is logged in the C:\Windows\Logs\CBS\CheckSUR.log file - and an archive …\checksur.persist.log file
Then zip the CheckSUR.log and upload it to your reply.
I *think* all the errors relate to the same problem - the Identity value data at
HKEY_LOCAL_MACHINE\COMPONENTS\DerivedData\Components\x86_8bc63dac42e4eabaca3593ddd2f5d84d_b03f5f7f11 d50a3a_6.1.7601.22110_none_3e4935d327505fbb
Let's see if CheckSUR agrees with me before I attempt to do anything :)
