How the heck does adding an option to Edge or feature to Paint qualify as an operating system update? The surround sound thing probably is tied to the OS, and the headset thing might be, too. Other than that, these are just software updates to things that people just don't need.
For God's sake, deliver the OS and the apps separately. Give the apps away in the app store or, if they're really worth a damn, charge a few bucks for them....however ya want. MS knows how to do this....Office, Minecraft, etc. If people jump onto an app and it becomes the "next big thing", then GREAT! MS should spend some effort making it available to Macs and Linux users, too, and profit away.
Just stop confusing updates to these applications as critical updates for the operating system. The average user out there probably isn't paying enough attention to know the difference, and making these updates appear important really just confuses the users when truly critical updates to the OS do get delivered.
