How To Log Into The Desktop, Add a Start Menu, and Disable Hot Corners in Windows 8
 

If you don’t have a touchscreen computer and spend all your time on the desktop, Windows 8’s new interface can seem intrusive. Microsoft won’t allow you to disable the new interface, but Classic Shell provides the options Microsoft didn’t.

In addition to providing a Start button, Classic Shell can take you straight to the desktop when you log in and disable the hot corners that activate the charms and metro app switcher.

There are other programs that do this, but Classic Shell is free and open-source. Many of the alternatives, such as Start8 and RetroUI, are commercial apps that cost money. We’ve covered Classic Shell in the past, but it’s come a long way since then.
