Windows 10 Version 21H1 Launches with Two Known Issues

Microsoft says mitigations already available for both

Windows 10 version 21H1, also called May 2021 Update, is now available for the first wave of production devices, though the company warns that some computers could be hit by a safeguard hold preventing them from downloading the new feature update.

And according to the official Windows 10 health dashboard, the May 2021 Update comes with two known issues, though Microsoft says mitigations already exist for both.

First of all, it’s the high-pitched noise glitch that has recently been confirmed in the previous versions f Windows 10 and hitting 5.1 audio with certain settings.

“After installing or later updates, 5.1 Dolby Digital audio may play containing a high-pitched noise or squeak in certain apps when using certain audio devices and Windows settings. Note This issue does not occur when stereo is used,” Microsoft explains.

The issue also exists on Windows 10 version 2004 and 20H2, and Microsoft explains that fixing this one comes down to streaming the video or audio using a different app or to disabling spatial sound on the OS.

Full fixes in the works

The second known issue concerns the automatic input of Furigana on a Windows 10 device.

“When using the Microsoft Japanese Input Method Editor (IME) to enter Kanji characters in an app that automatically allow the input of Furigana characters, you might not get the correct Furigana characters and might need to enter them manually. Note for developers: Affected apps are using the ImmGetCompositionString function,” Microsoft says.

Users impacted by this glitch need to revert to a previous version of an IME. Microsoft confirms that the bug also affects the previous Windows 10 versions, namely 2004 and 20H2.

In both cases, full fixes are already in the works, and Microsoft explains they should be part of an upcoming release, though no further specifics in this regard have been provided.
