I'm not aware of the way to do that. I tried right clicking on the search result icon "regedit," right clicked, then clicked delete but that was ineffective. Also, when I type regedit in the search line and it is listed I can then click on "run command" and it opens regedit. I am also able to open regedit by going to accessories, run and doing so. It just gives me the error message if I click on the search result icon with regedit.
