Re: It's a start...
They are not stopping you, you can create another Microsoft account, like you can with any other company, buy software, like from any other company. You just don't get to link it to your Corp account like you cant with all the other software you can buy.
If you buy software randomly you don't get support from your IT support, like you shouldn't, IT departments are usually under funded and under staffed, having people buying random crap, and then expecting it to be supported is moronic.
