OH thank you thank you thank you !!!
it worked!!!
Well that is good news, but......
It worked, in what sense?
That would have been the fastest bit of troubleshooting I've seen lately, if you've already completed the entire process, found the offending culprit and dealt with it specifically and only it.
Performing the steps in the initial Clean Boot process will generally help set things straight as you're turning off Start Up items and stopping NON-Microsoft services, however.....
That is when the work starts. Putting things back that you may need (maybe), one by one to identify the bad guy.
If you did in fact truly figure it out that fast....
First of all I'll extend a "congratulations" and a "good work".
AND
Ask, which particular program, process or service was it? As that information may very well help others with similar issues.
