Thanks! Now I'm definitely buying our new PCs with Win 8(8.1) specially since Win 7 is not easy to find these days. The Win8 Pro downgrade option is something I wish I knew when we bought a couple of Win7 PCs a few months ago.
Now, Is it worth to upgrade our old PCs? So far it doesn't seem so, but I may upgrade just one to try it myself with dual boot or something. Martin
