I don't think this is a PR move. This looks like a new business model that finally acknowledges the facts on the ground. OS version upgrades for consumers are either free and mostly automatic or they don't happen. It's not just a Windows phenomenon. I'm sure 90% of Android users would never pay for and actively install an Android version upgrade. Even OS X upgrades are now free, supposedly for the same reason. So if Microsoft makes very little money on consumer version upgrades anyway, they could just as well let everyone use the latest version for free and make life a lot easier for themselves and for millions of developers. It's a very welcome move that is long overdue.
