Microsoft recently pushed Windows 11 KB5008215 through Windows Update, which is part of the December 2021 Tuesday patch. At the same time as pushing the patch, Microsoft also released the download address of KB5008215, which users can manually download to install the update.

With the release of this new patch,The Win11 system introduces a new emoji, which is compatible with Microsoft's current Fluent Design design style.

The new emoji will align the style of the operating system with other Microsoft products such as Skype, Teams, and more. These emojis have a more modern design and the series looks good, but they are still 2D emoticons.

Previously, Microsoft had promised to provide 3D emojis for Win11, but apparently that promise remained unfulfilled. In addition, Win11's new emoji set also includes a classic-style paper clip.

If you're a long-time Microsoft user, you should know the classic paperclip controls, which were once classic elements of Office. Microsoft recently asked users if they wanted to see paper clips in the operating system, and quite a few people favored the classic style emojis of paper clips.

In terms of bug fixes, KB5008215 fixes an issue where one drive becomes slower.

If you check for Windows Update updates, you can find a patch called "2021-12 Cumulative Update for Windows 11 for x64-based Systems (KB5008215)".

Here are the important changes to Windows 11 (Build 22000.376).

Fixed an issue where file explorer and desktop shortcut right-click menus might not pop up.

Fixed animation of taskbar icon.

Fixed Bluetooth audio issue.

Fixed various issues with File Explorer.

Fixed an issue that affected start menu performance and reliability.

Fixed a performance issue with the storage drive.

It should be noted that the performance problem of the storage drive has been plaguing users for a long time, and today it has finally been officially fixed.

As early as August, users reported that storage drives were too slow to write, and according to reports, Windows 11 had an impact on write speeds of up to 55%, which in some cases can significantly slow down machines.

This issue was first flagged during public testing, but it seems to have been somehow ignored, and the issue also appeared in the stable version.

Performance comparison between Win10 (left) and Win11

As the screenshot above shows, Win11's write speed is significantly slower than Win10's. In some cases, users can also observe that Win11's read speed is also slow.

Win11 Build 22000.376 also fixes other issues.

According to the release notes, Win11 Build 22000.376 fixes an issue where Internet Explorer stops responding when a user pastes copied text.

Microsoft also fixed an issue where file explorer and desktop shortcut menus would not be displayed when a user opened an item with a single click.

The stability of the filer has been improved, fixing an issue where the file manager stops responding when closing a window after browsing a directory.

Also fixed a bug where the desktop right-click menu was affected when creating shortcuts for applications using a directory tree or background.

Microsoft has modified the volume control for Donghua and Bluetooth audio devices in the taskbar.

However, Win11 still does not support direct drag-and-drop pin icons for the taskbar. The taskbar issue fixed by this Win11 update is mainly about the problem of flashing when the mouse hovers over the taskbar icon.

Other fixed issues are as follows.

Fixed a rendering issue with closed subtitles in some videos.

Fixed an issue that could affect the performance of task view, Alt-Tab, or Snap assist

Fixed an issue where turning off the presence sensor option of the headset could cause Windows Mixed Reality to get an error.

Fixed a bug that could cause audio to be temporarily lost.

Fixed an issue with font rendering.
