Less than 24 hours after it delivered build 15060 to Windows 10 Insiders on the Fast ring, Microsoft has shipped yet another build, 15061. RC3, anyone?

So Microsoft has now shipped three builds this week: Build 15058 on Tuesday, build 15060 on Thursday, and now build 15061 today (Friday). Whew!

Like the previous several builds, Windows 10 Insider Preview build 15061 doesn’t bring any new features. Instead, Microsoft is completing the development of the next major Windows 10 version here and is just fixing bugs at this point.

You can check out the original Microsoft blog post for a list of changes, improvements, and fixes, and a separate list of known issues. Neither is very long.
