This tweak tells Internet Explorer to simply 'run', without loading any webpages. If you use a 'blank' page, that is still a page, and slows access. Notice the 'about:blank' in the address bar. The blank html page must still be loaded.
To load IE with 'nothing' [nothing is different than blank]:
1. Right-click on any shortcut you have to IE [You should create a shortcut out of your desktop IE icon, and delete the original icon]
2. Click Properties
3. Add -nohome [with a space before the dash] after the endquotes in the Target field.
4. Click OK
