In addition to pushing out a boatload of new Surface hardware yesterday, Microsoft also made the October 2018 update of Windows 10 generally available--it should be heading to your machine soon if it isn't there already. Here are all the new features you're going to be able to take advantage of with the new update. This being Windows, of course, there are dozens of little tweaks and improvements spread across the vast amount of code that makes up the operating system, but these are some of the most significant differences you'll notice. The biggest upgrade arriving with Windows 10 is the Your Phone app, which you can find from the Start menu. If you remember the old Phone Companion app, it does something similar--essentially making it easier to use Windows 10 and your smartphone together.
