Microsoft has today released the new preview build for insiders in the fast release. The new build is 10547 and is now available for download. As usual, this build includes bug fixes and improvements over Build 10532 and also includes some new things.
The new build has some interesting improvements to the start screen. If you are in the insiders program you can now install this build. Here are the new features.
Improvements to Start:
The default for tile groups on Start is to have 3 columns of medium sized tiles, but now Microsoft has changed it based on the feedback and now it is set to 4. So now, they could have two wide or large sized tiles side by side in a group. In this build, you can enable this by going to the Settings app > Personalization > Start and enabling “Show more tiles”. And for the Insiders that want more than 512 tiles on Start; we now support up to 2048.
Improvements to Tablet mode:
When in Tablet mode, from Task View you can now snap apps to left and right, replace a previously snapped app with another (teeter) and swipe down to close an app.
You can now turn off the Windows background picture in the sign-in screen if you want by going to the Settings app > Personalization > Lock screen and turning off “Show Windows background picture on the sign-in screen”.
There are lots of other bug fixes in this build. More details available here.
