After nearly two months without seeing a new build, Slow Ring Insiders can now download the Windows 10 Insider build 17115. This is the latest RS4 build that rolled out hit the Fast Ring earlier this week, so Fast and Slow Ring insiders are once again on the same page today.

The last time Slow Ring Insiders got a new build was January 19, when Microsoft rolled out the Insider build 17074.1002 to them. Since then, newer builds have introduced new font settings, a new privacy set up experience, as well as plenty of improvements for Windows Shell, Microsoft Edge, Game Bar, app permissions settings and more.
The Windows Insider team also plans to release an ISO for build 17115 "early next week," and we'll let you know as soon as it happens. The "Spring Creators Update" is now almost fully baked, and future builds should be all about polishing things for the public rollout in April.
