and searched for this, "Trusted Installer" thread you started. Sorry.
Not sure why the HelpDeskGeek method failed for you, except I know that permissions got harder in Win 7 and I never even got a handle on it in the {supposedly} easier XP.
I know you are keen to remove 'all traces' of unwanted items on your OS, so I won't even suggest to you that these folders are harmless and could remain, or that there is always the risk of damaging the OS when changing the registry.
No, I won't mention that, ![]()
How about this; Try using Windows 7's "Hidden Administrator" account. You need to enable it first;

And I would disable it afterwards.
See if that works.

I am at war with Trusted Installer. I want to delete two Windows Mail folders that were not removed when I uninstalled all of Windows Essentials from Programs and Features. I have good instructions from http://helpdeskgeek.com/windows-7/windows-7-how-to-delete-files-protected-by-trustedinstaller/. I took ownership and granted myself full control permissions. However, I get the popup telling me I need permission from the Administrator (me)......usually when I see this message, I click "Continue" and proceed....but I am not allowed to proceed in this situation. The proper owner name change is listed in the Windows Mail Properties.
