As I thought - it's almost certainly a bitflip in the registry causing the manifest error.
The S256 hash value differs from the found value by only one bit....

Expected:{l:32 b:8e98bc15c20c1b3cd3e871c52786e47815e132c0ade91cbdaba5da9f2fb29bc3}
Found: {l:32 b:8e98bc15c20c1b3cd3e871c52786e47855e132c0ade91cbdaba5da9f2fb29bc3}

It's almost impossible for that to happen with a corrupted file, so the value in the registry must be wrong.

I'll adjust the COMPONENTS hive accordingly (after checking the value elsewhere) - that should get rid of the rest of the errors

OK - done and confirmed... and we have an easier way to fix it than messing around with detached COMPONENTS hives

Open an Elevated Command Prompt and run the following commands

Code:
 
REG LOAD HKLM\COMPONENTS C:\Windows\System32\config\COMPONENTS
REG ADD HKEY_LOCAL_MACHINE\COMPONENTS\DerivedData\Components\x86_mdm5674a.inf_31bf3856ad364e35_6.1.7600.16385_none_e6de8df1e7b331d5 /v S256H /t REG_BINARY /d bc15c20c1b3cd3e871c52786e47855e132c0ade91cbdaba5da9f2fb29bc3 /F
REG UNLOAD HKLM\COMPONENTS
close the window, and reboot - then run another SFC scan and post the CBS.log

Hmmm -
Code:

Odd - I seem to have 'lost' the first two Bytes of data from the expiated value for the S256H....
let me try that again......

In an Elevated Command Prompt, run the following commands.

Code:
 
REG LOAD HKLM\COMPONENTS C:\Windows\System32\config\COMPONENTS
REG ADD HKEY_LOCAL_MACHINE\COMPONENTS\DerivedData\Components\x86_mdm5674a.inf_31bf3856ad364e35_6.1.7600.16385_none_e6de8df1e7b331d5 /v S256H /t REG_BINARY /d 8e98bc15c20c1b3cd3e871c52786e47855e132c0ade91cbdaba5da9f2fb29bc3 /F
REG UNLOAD HKLM\COMPONENTS

We also seem to have picked up another manifest problem.

Please run CheckSUR again, and post the new log

Appologies for the delay, had a few other issues that had to take priority.
Thanks for your support so far.

My windows 7 is constantly crashing.
My Windows 7 is constantly crashing during video games and streaming shows. There isn't a BSOD it just shuts down then reboots. Even then it doesn't always reboot all the way. I have tried restoring and antivirus scans though I can't seem to pinpoint the source. Any help or advice would be helpful.
