Microsoft is releasing a new build of Windows 10 to Insiders in the Fast Ring today. The company is today pushing out build 17107, a Redstone 4 build, to all Insiders in the Fast Ring.
Redmond released the first ever Redstone 5 build to Insiders part of Skip Ahead last week, although the company isn’t releasing any Redstone 5 build this week. So the latest build is only for those still in Redstone 4.
In terms of new features, there isn’t much to be excited about. There is, however, a critical change to how Windows Update works. Right now, your device will go to sleep when it’s inactive while Windows Update is downloading a new update, which could slow down the installation process in some cases. This is something that annoys me quite a lot when installing Insider builds on a test machine as I only use those for testing out new features and they are mostly not in active use. With this update, however, Windows Update will keep your PC awake for up to 2 hours as long as your device is connected to power, which should speed up the installation process without any interruptions. Phew.
There are some other general improvements and fixes included in 17107 — you can find the full changelog here.
