Thanks for the link, BUT the procedure doesn't match the 64 bit W7 regsitry editer they date from 2009.
On my 64 bit W7 desktop, I ran a most aggressive Registry Cleaner scan and a few of the deep scan items could not be deleted by PowerTools (version 1173). The items' owner was TrustedInstaller, which was the only ID with full control.
You are right about the procedure. At least in this case, the window presented at Step 3 was different (*); specifically, it had no tabs. It is not real intuitive what one should do with this window. However, there is a button near the center of the right side of the window. I believe it's caption was "Start Search." Clicking it caused a list of entity names to appear.
If you select your user ID from the list, you should be able to get to the window with the Owner tab, assign ownership to your ID, and give it full control.
I did that with the item shown below, and the item could then be deleted by PowerTools.
Windows Registry Editor Version 5.00

(*) I tried the procedure's Steps 1 and 2 with several other randomly chosen registry keys. In every case, the window presented at Step 3 was the one assumed by the procedure.
