Go here: http://www.newprofiledisabler.net/ There's an APP for THAT! (ha ha ha, sry couldn't resist!) On the upper right of that page is a big button that says "Install Now", click it! (for chrome. if you have firefox or opera, click the links to go to them. ) On the bottom of your browser window the download will appear, asking if its ok to run. Say yes, and a new window will open. Close your brower and refresh. DONE!
