I'm logged on as Administrator; it is only account on the computer.
Recently I found I could not access many system admin tools and when I try I get error of you may not "have the appropriate permissions"
This applies to "Services" "Component Services" "Computer Management" Also get same error when I click on Desktop Computer Icon and select "Manage"
Running Win 7 Home with all latest updates
Note that I'm not trying to access anything via a network but simply access, as administrator, the settings in my installation of Win 7 itself.
