Hello Windows Insiders, today Microsoft is releasing Windows 10 Insider Preview Build 19564.1000 to Windows Insiders in the Fast ring. 

This build is a post 20H1 build and is from the active development branch of Windows 10 at Microsoft. While features in the Active Development Branch may be slated for a future Windows 10 release, they are no longer matched to a specific Windows 10 release.

What’s new in Build 19564

Graphics Settings Improvements

Microsoft has updated the Graphics settings page (Settings > System > Display > Graphics settings), allowing for better control over designating which GPU your apps run on. With this update, the app list and GPU preference are pre-populated on a best effort basis to improve the default preference management experience. If your desired app isn’t pre-populated, you can still add it by using the app selection drop-down.

You’ll notice alongside this, Microsoft has also added a search box and a filter for the list of apps.

Microsoft has been working on an improved version of the Calendar app for Windows 10 and the preview is now available to Windows Insiders! Here is a sneak peek of what’s new in the preview:

  1. New themes: choose from over 30 different themes!
  2. Improved month view: Month view now includes an agenda pane that lets you see your day’s events at a glance.
  3. Simplified event creation: Microsoft has made it even easier to add an event to your calendar.
  4. Redesigned account navigation: Microsoft has collapsed the account navigation pane, leaving more space for your day’s events.       All of your syncing calendar accounts are now represented as clickable icons on the left.

You can try the preview by going to the Calendar app and selecting the toggle to try the new experience. Don’t worry, you can always switch back at any time! Microsoft are excited to hear what you think of the new experience.
