After some months of sporadically trying to access a Microsoft Account or the Store on my Dell Inspiron 660 without success (along with some 1000's of other Win8 users according to M.S. blogs), plus its incompatibility with *all* of my USB external audio interfaces in spite of driver updates, the time has come to downgrade to Win7 from the preinstalled Win8 Home. I am assuming the software is the problem as the hardware works fine otherwise and everything will work in Win7.
Thus, the question is will any commercial version of Win 7, eg. from Amazon, be 100% compatible with this machine, or are there some tricks with the bios that would need fixing. Is there is a Dell configured version of Win7 to purchase.
