Hi try this.......Right click on your internet explorer icon on your desktop........Click on Properties on the drop down menu.....In the Browsing History section Click on DELETE.........On this screen on the password section click on DELETE ALL.......On the small window that appears check the box and click YES......This will now clear a hell of a lot unwanted bits of files.......Try now to go to goole on the internet and search for a free reg clean program and use.....Hope this helps
