Or simply install
Classic Shell or
Start8 Start Menu replacement app, set them up to boot directly to the desktop, disable the Hot Corners on the desktop and make this dynamic OS (Win 8) look and feel like Win 7 with the added security that comes with Win 8.
You would not be able to tell I have Win 8 installed (replaced Win 7 when Win 8 was released) unless I showed you how.
I installed EVERY app that was working on Win 7 onto Win 8 with no problems at all. In fact Win 8 networks better on my home network, and is much faster than Win 7 was.
