Win 7 X64 spooler issues.

Have a machine running Win 7 home premium 64 bit, it had an HP MFC printer connected to it but then suddenly stopped working.

Some hours of looking about found the problem was the spooler service stopped starting,
checked c:\windows\system32\ and found spoolsv.exe was renamed spoolsv.exe.log, removed the wrong version of spoolsv.exe and put back in the correct version and spooler started up fine.

Problem is that every time the machine reboots the problem repeats itself. On checking the event log, aside from the message that the spooler failed to start the only other error I get is:
The Remote Procedure Call (RPC) Sync failed to start due to the following error:
This version of RPC Sync is not compatible with the version of windows you're running...


Any ideas on if the two are related and how to resolve the spooler problem?

I'd rather do a restore as a last resort, I'd prefer to know if this problem will re-occur and how or why it happened.

SFC scan says it found corrupt files but was unable to fix. Posted to the cbi.log but beyond me as to what in the log to look for exactly.

Ok running out of fingers to count the number of times I've run SFC

Looking at the log it seems to be tcpmon.ini that is causing the problem, here's an excerpt
