Windows 10 Insider Preview is rolling out now. This is a significant update that brings not only fixes but some changes and improvements as well. There are also a number of known issues already that will be fixed in future updates.
The most notable change in this update is the retirement of the Internet Explorer 11 desktop application. The full version of Internet Explorer 11 is set to be retired in June 2022. Thus this is just with regards to the desktop app itself.
Internet Explorer 11 has been with us since the very beginning of Windows 10 even though Microsoft had plans to replace it with a better browser that was based on a more structurally sound foundation. Microsoft chose to build their new browser — named Edge — on the Edge HTML code. Edge turned out to be unsuccessful and needed to be replaced with a Chromium foundation for better website compatibility.
Version 21387.1 comes with the following changes and improvments:
- The Internet Explorer 11 desktop application is now retired as of this Insider Preview build. For additional details see https://aka.ms/IEmodeblog.
- We are turning off the “Eco mode” feature in Task Manager in order to refine the experience and address several issues thanks to Windows Insider feedback.
Version 21387.1 brings the following fixes:
- We fixed an issue in the previous flight where during the upgrade and in the welcome screens displayed after first sign in, the text was unexpectedly using the Times New Roman font.
- We fixed an issue resulting in some Insiders seeing errors when trying to launch Notepad via the Run dialog.
- We fixed an issue for WSL users, preventing some Linux GUI apps from launching correctly via the shortcut that is automatically added to Start menu.
- We fixed an issue resulting in the reset or change PIN workflows not working.
- We fixed an issue where for some Insiders, night light was immediately turning off after being enabled.
- We fixed an issue in recent flights where you might unexpectedly get a “We can’t find an audio device” error when trying to play audio from a connected Bluetooth speaker.
- We fixed an issue where explorer.exe might crash after repeated use of the touchpad gesture for switching Virtual Desktops.
- We fixed two issues impacting the ability to print using USB printers.
- We fixed an issue resulting in the Windows Update page potentially becoming unresponsive after clicking Pause Updates.
- We fixed an issue causing some devices to fail with error code 0xc1900101. While this fix will resolve the problem on some devices, there is a second issue causing the same error code (noted below). We’re working on a fix for this issue as well.
- We fixed an issue where some devices were re-offered the .NET update after it is installed. After taking this build you should no longer be reoffered the .NET update. If you experience and issue getting Build 21387 because of a pending .NET update, you can work around the issue by pausing then un-pausing updates.
- We fixed an issue where some devices would crash with a DPC_WATCHDOG_VIOLATION error when using OneDrive Personal Vault.
- We fixed a ctfmon.exe crash when using ATOK (a third-party IME) if reconversion was triggered in some win32 apps.
And version 21387.1 has the following known issues already:
- The Windows Camera App currently does not respect the default brightness setting set via the new Camera Settings page.
- We’re investigating an issue where elements of Search (including the search box in File Explorer) are no longer displaying correctly in dark theme.
- [News and interests] We’re investigating an issue where the flyout may occasionally flash in the top left corner of your screen after clicking the button on your taskbar.
- We’re working on a fix for a second issue causing some devices to fail when updating to this build with error code 0xc1900101. When the update fails, it will roll back to the previous build. If you are encountering this issue, we recommend pausing updates until we release a build with the fix.
