End the “explorer.exe” task. All the windows will be closed down. Don’t panic. You can still see the command prompt.

Speed up IE Start Up

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
