I have one machine that is running my MSA and is on the insider program.. I'd like to change my other genuine machine to also be on the insider program.. Is it just a matter of logging in to that machine using my MSA or have i missed the boat? Edit : Think i've answered my own question... i jsut did a fresh Vm install.. no key and went to updates.. there's a nice button that says Get Insider Previews. Edit 2 : Ok.. so it's not activated.. is that going to cause me problems?
