Steam always fails on me when I want to install to another location so far. Regardless - steam mover can move em back again too, so you could have the current faves on SSD but shift them away when you're about done with them, don't think Steam does that.


So: install Win 8.0 then update?

Not had any problems here, I am in the Family Sharing Beta (not that I have any "family" to share with), so maybe they've fixed it in that?

Yes, install Windows 8.0 and update through the store.
