Windows as a service
The most interesting announcement was "Windows as a service". Still trying to find details as to what Microsoft means with that, but my guess is that it will work as any other "as a service" offerings. Instead of paying for a one time license fee and having the right to use the software indefinitely the charges will come monthly and in the end everyone will pay more money than with a one time license model. Even if each Windows as a service account will be charged 5$ a month it will be 60$ a year, after a bit more than two years everyone will be paying more than before and keep paying. It will also be no longer possible to cling to trusted old versions that do the job well (as XP, Win 7 are). Microsoft will stuff new things into Windows as a service and make changes and as a user you either like them or you don't. And if you don't, good luck switching to a different OS or rolling back.
On a different topic, a better browser from Microsoft is more than welcome. IE11 just stinks, but the decision to keep IE11 is horrible. Offer it as an extra download for free, but otherwise please put this utterly dysfunctional standards ignoring piece of software junk out of its misery...and make users happy at the same time. That will also be the kick in the pants for all those who insist on using IE-only browser based apps to finally move away from that dead end.
