Windows 10 is out today! This is the first release of Windows that I have worked on as a developer , and I'm proud of what my team and Microsoft as a whole have accomplished in the past year-and-a-half or so. Several tech websites have already posted reviews, and so far the trend is very positive. A colleague of mine posted some excerpts, which I'm going to borrow:

Windows 10 represents the obvious future of PC operating systems. It makes Mac OS X feel old-fashioned, stuck in a time where The Desktop was a thing that mattered and the only way to access the Internet was through a browser.

So the question finally presents itself: should you upgrade your machine to Windows 10? Yes, you should.

The best part of Windows 10 is that it ends the cycle of good and bad in favor of something great.

It's nice, for once, to be able to recommend a new version of Windows without any hesitation.

If you are on a PC at all, Windows 10 is where you want to go. That it is free—for now—only makes the point simpler.

If you haven't already done so, you can follow the instructions here to get your free upgrade. It's very exciting to have played a role in the creation of the latest and truly greatest version of Windows; I think this is a huge achievement for Microsoft, and I'm happy to have been a part of it. The real reward, though, is seeing people use and enjoy Windows 10—and that starts today!
