Click on the start orb and type msconfig in the search box. Click on msconfig.exe, Select Diagnostic startup click Apply then click OK. Restart with the prompt and see if the issue is still there.

Windows 10, Home Clean Install

OK Im back
IM familiar with using the clean boot. Start with that
How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

If clean boot starts at 100% usage, try in safe mode.
We want to determine the cause.

Outlook has a high cpu usage too. Remove that from start up or turn it off.
Disconnect from the internet, lets make sure that it is not something really bad

Rerun malwarebytes. Full scan and updated

0710 CT - Thankful

Today will be a tad busy. However, I have all the 'pieces' to try and narrow this down with the startup limitations.

I have also discovered in the meantime, additional unattributed "iexplore.exe" that will not die. All are the 'SCODEF:XXXX CREDAT:XXXXX' variety. Using PID and Command Line, I'm confident I'll be able to begin the slaughter.

With a full magazine of information, I'm anxious to return and finish the assault on these resource hoarders, but alas, the pre-Thanksgiving preparations force me to wait until hopefully later today.

Once again, I can't thank you enough for the valuable input and will check email and this forum until this annoyance is a memory. Then I can move on to other perplexing issues. Having worked alone on this stuff for so long, continually reinventing the wheel and searching dark alleys, it's amazing to see the prompt, solid assistance to seemingly pop out of nowhere. More knowledge in a few hours than weeks or months of trial and error.

This is really a time to give Thanks. For those about to feast...

It's not going to help tremendously but uninstall all of that google stuff for starters.

You may also want to look into BootVis since many of your processes seem to be running on startup you can shave some stuff off there.

If you dont use BackUpNow any longer remove that too.

And Lastly, try running Outlook in safe mode. See if it still eats all of that ram to run. If it doesnt then you know you have a plugin or something that is causing this. In the "search Programs and Files' box on start menu type in "outlook.exe /safe"

Windows 7 Ultimate 32bit
Problem Solved...

Apologies for the delay. Holiday season, etc, etc...

My failure to keep a detailed log of my repair efforts clouds the picture of exactly which step(s) finally tamed my overactive CPU; however the general indicators/culprits remain clear. Without question, the success is completely as a result of suggestions presented within this thread.

If my CPU was human, one might have suggested Ritalin. However, it appears the strongest indicator(s) of success point to Outlook and the massive number of startup processes.

While boot time was never a huge factor (actually my "racing" CPU gave the impression it couldn't wait to get into the game), and I've used machines where, while waiting for a full boot up, you could go make and eat a your friend's house across town. Then the ‘welcome’ screen would appear, like clockwork, while reading the last paragraph of an un-translated copy of War & Peace.

In this case, disabling add-ons in Outlook is the most likely remedy. Observing Outlook’s activity in Process Explorer, you could see a steady increase in resources. It would begin by consuming approximately 250MB and ramp up to nearly 0.5GB. Now Outlook is holding steady in the 90MB range. One curious change: UAC now asks for permission to open the program. I did not notice its absence until its appearance.

There is one phenomena that seems to defy explanation; at least to me. When all meters indicated CPU usage pegged off the scale, it would require killing several heavy hitter processes, including Outlook, to bring demand down to even 90%. This would seem to push the scale back toward the elimination of extraneous startups.

Perhaps the largest lesson learned here, excluding the fix itself, is the need to develop the patience to detail the recovery process so those that follow might possibly be spared from having to reinvent the wheel. Fortunately, they may only have to look at the posts contained here.

Clearly the answer(s) to my predicament lies within this thread, and for that I am indebted to each and every one of you.

Thank you.

The answer has to be in Process Explorer. It show usage at any given point in time.
How about completely unattach the net. See if it is the source. Not turn off, unattach.

I'm unsure how to "unattach the net" (or I'm unfamiliar with the term), however, as requested, here is a Process Explorer screen shot following the fix:

If you are connected to the net by cable, unattach the cable.

I'm still chuckling at my ignorance. What else could "competely unattach the net" mean? pfffftttt. I suppose sounding stupid helps keep a person humble. I am a living, breathing example of the quote in your "signature". I'm just hoping my five minutes is up soon. It is comforting to know that there is assistance
available for the feeble minded. Otherwise, I'd be SOL. Now, if everyone's eyes have quit rolling...

This screenshot is after...ahem, unattaching the net, which in my case meant simply pulling the wireless USB adapter (sheesh):

That screen shot looks fine
Lets see if memory is actaully ok
Run for 8 passes. Check each slot with a good stick, when done

Download and test RAM with Memtest 86. Test each RAM stick separately, for 6 passes. Then with a known good stick test each RAM slot.
