Is it possible to upgrade a Windows RT device to Windows 8? Or any windows that is not RT Lenovo Yoga 11?

I'd not try that… Reason… You only have 2 gig ram… I have win 7… The windows folder alone is 26 gigs… The 2 windows program folders total 54 gigs… And then there are the other miscellaneous folders… Your little toy has only what… 64 gig total?
So… No to the upgrade…
