Why pay, just get Start Menu 8. Gives all features of the above, takes out Metro completely (Heck it even did that with Win8), and it has the best price of them all, FREE! It is one of IOBit's offerings.

Have you ever considered one of those programs like Start8, Power8, Start Menu Reviver, etc? http://en.wikipedia.org/wiki/List_of_Start_Menu_replacements_for_Windows_8[^] has a bunch of freeware listings of programs of this sort. One common theme is turning off the charms, restoring the start menu to a Win7 state (yet still using win8, course with the fully functional start menu back you don't even need the charms), and most will bypass the Metro startup, going into the Windows desktop at startup. I got sick of the whole thing early, but didn't have a Windows 7 install CD. However, for the sake of staying legal, a friend suggested this option to me.

It follows in that same concept where the study of computer science actually has nothing to do with computers, simply what could be done with computation of data.
