Today Microsoft released Windows 10 Insider Preview Build 18898 (20H1) to Windows Insiders in the Fast ring.

Here’s what’s new in the latest build.

Disk type now visible in Task Manager Performance tab

A small, but perhaps convenient change — you’ll now be able to see the disk type (e.g. SSD) for each disk listed in Task Manager’s performance tab. This is particularly helpful in cases where you have multiple disks listed, so you can differentiate between them.

General changes, improvements, and fixes for PC

• Microsoft fixed an issue resulting in a high hitting DWM crash in recent builds.
• Microsoft fixed a pcshell.dll issue in recent builds resulting in a high hitting explorer.exe crash.
• Microsoft fixed an issue where updated Japanese IME settings would be never applied in certain desktop bridge apps, which could result in prediction candidates being shown even after they’d been disabled in the IME settings. For those who’ve already been impacted by this, you’ll need to reset the app Settings > Apps > <select the app> > Advanced Options > Reset before you see the results of this fix.

Known Issues

• There has been an issue with older versions of anti-cheat software used with games where after updating to the latest 19H1 Insider Preview builds may cause PCs to experience crashes. Microsoft is working with partners on getting their software updated with a fix, and most games have released patches to prevent PCs from experiencing this issue. To minimize the chance of running into this issue, please make sure you are running the latest version of your games before attempting to update the operating system. Microsoft is also working with anti-cheat and game developers to resolve similar issues that may arise with the 20H1 Insider Preview builds and will work to minimize the likelihood of these issues in the future.
• Some Realtek SD card readers are not functioning properly. Microsoft is investigating the issue.
• If you use remote desktop to connect to an enhanced session VM, taskbar search results will not be visible (just a dark area) until you restart searchui.exe.
• Microsoft is investigating reports that on certain devices, if fast startup is enabled, night light doesn’t turn on until after a restart. (Note: The problem will occur on a “cold” reboot or power off / power on. To work around if night light doesn’t turn on, use Start > Power > Restart.)
• There’s a noticeable lag when dragging the emoji and dictation panels.
• Tamper Protection may be turned off in Windows Security after updating to this build. You can turn it back on.
• Some features on Start Menu and in All apps are not localized in languages such as FR-FR, RU-RU, and ZH-CN.
• In the Ease of Access settings, selecting a color filter may not take effect right away unless color filters option is turned off and back on again.
• The IME candidate window for East Asian IMEs (Simplified Chinese, Traditional Chinese, and the Japanese IME) may not open sometimes. Microsoft is investigating the issue. In the meantime, going to Task Manager and ending the “WindowsInternal.ComposableShell .Experiences.TextInput.InputApp.exe” task from the from the Details tab should unblock you if you experience this issue.
• Microsoft are aware of an issue with the Bopomofo IME where the character width is suddenly changed to Full width from Half width and are investigating.

Known issues for Developers

• If you install builds from the Fast ring and switch to either the Slow ring or the Release Preview ring, optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.

Windows 10 Insiders in the Fast Ring can download the update by Checking for Updates in Settings.
