BITS Service won't start Error 0x80070002

Hi guys,

I have a nasty problem on Windows 8.1

My BITS Service won't start (and therefor Update, Store, etc are all down).

Event log shows two error events;

The BITS service failed to start. Error 0x80070002.
The Background Intelligent Transfer Service service terminated with the following service-specific error:
The system cannot find the file specified.

Addditionally another error appears every now and then:
The ScRegSetValueExW call failed for FailureActions with the following error:
Access is denied.

I've tried so far:
wsreset.exe
Windows Update Troubleshooter -> first few times it just said it coudn't fix my problem, now it just hangs on starting BITS
sfc /scannow -> no errors found
Microsoft FixIT for Win Update
System Restore
Refreshing the image using DISM
I checked all the registery keys for BITS with another build 9600 pc and made them matching, no effect.
I cleared the Data Store folder and restarted Win update serv, no effect on BITS

Any thoughts?

Sorry for doublepost, found a possibly related error in event log:

The server {4991D34B-80A1-4291-83B6-3328366B9097} did not register with DCOM within the required timeout.

Source: DistributedCOM

The ScRegSetValueExW message is a reasonably common error message, and one that can usually be safely ignored. I've noticed it when installing or uninstalling software and is related to an application trying to access a portion of the registry it shouldn't be.

Have you tried a malware scan on the machine? BITS is a fragile service at times - given the file not found message, it might be worthwhile trying to start the service whilst running Process Monitor (available from TechNet, previously a Sysinternals product) to see exactly what Windows can't find.

I have ran a virus check with Panda. I'll try the process monitor a try and report back.

EDIT: I've never used this program, what exactly am I looking for?
