Pretty good article that makes a good point about MS and the reason's for free upgrades.
The free OS "Upgrade" will be for the life of the computer you are updating, if you build a new computer, you buy a new license. Make's sense, I just hadn't thought of it, LOL.
" People will still buy or build new PCs, and those new PCs will still need Windows licenses. Those Windows licenses will, for the time being, still cost money."
