The company does well to continue improving the reviewer experience for the select few who get to sample these OS enhancements before anybody else. If you are in the Fast ring, you can install the Windows 10 Insider Preview Build 19564.1000 that Microsoft released earlier today. Build 19564.1000 introduces a set of features, and it fixes a couple of bugs. Microsoft said that, after installing this build, you may later update it via Windows Update. The cumulative update for this build does not include any coding enhancements because its only purpose is to help Microsoft test its “service pipeline.” As such, it does not add features or change the way you use existing Windows 10 applications or utilities. Build 19564 includes the following enhancements:

GPU control

As a Fast ring Windows insider, you now have more control over how your apps utilize your system’s graphics processing power. This build features a pre-populated app list with default graphics settings for each application. Microsoft said that the system employs a “best-effort” approach to determine which app gets what GPU preference by default. Better GPU control comes in handy for PC users who regularly use a mix of graphics-intensive applications, such as 3D modeling and rendering software, and apps that do not stretch their machine’s GPU capabilities. If you do not like the GPU preferences assigned to your apps by default, you can change them at any time at the “Graphics settings” page via Settings > System > Display. The default preference for each item in the pre-populated list is “Let Windows decide.” Choose “Options” to customize it. You may even add an app that is not in the pre-populated list by clicking the drop-down under “Choose an app to set preference.”

The search box lets you find apps in the list. The update also introduces an app filter.

Fixes

One of the fixes available with this update involves restoring East Asian IMEs to the language/keyboard switcher. The IMEs disappeared after users upgraded from 20H1 Build 19041 or lower versions to Windows Insider Preview Build 19536 or later updates.
