Thank you Shane for moving this question, and for your response.
On my W7 SP1 system I run Malware Bytes Pro and BitDefender.
I have run ADWCleaner from time to time.
All 3 come up clean when I run scans.
The 1st few times I ran your tool I did run all the steps, and always in Safe Mode with Networking.
What I noticed was that I would run your tool, do a Windows Update on one sub-set of updates, and have the updates run successfully.
Then, the symptom I described (svc.exe running at 99% of my cpu) would start again.
So, I did the following: run your tool (steps 1,2, and 17); apply a subset of WU patches; run your tool (same 3 steps); and repeat these steps until all WU patches had been applied.
It was a "brute force" method; but my system runs fine now.
So, from that point of view, I think you can call this problem "fixed."
Thank you,
Dick
