With today’s Patch Tuesday release, Windows 11 is finally getting some new emoji that are compatible with the company’s Fluent-style approach. The new emoji would keep the operating system in line with the rest of the Microsoft products, such as Skype, Microsoft Teams, and more.

The emojis have a modern look and they’re in line with the overall design of Windows 11 and the collection is pretty nice on the whole. Of course, these are 2D style emojis despite the tech giant promised 3D emoji for Windows 11. As expected, Windows 11’s new emoji collection also includes Clippy as the replacement for the paperclip emoji.

KB5008215 features

For those unaware, Clippy was part of the Microsoft Office suite in the early 2000s and it is back by popular demand. Microsoft recently asked users if they would like to see Clippy in the operating system and a sizeable number of folk had voted in favour of the iconic assistant’s emoji.

KB5008215 fixes performance issues with storage drives

Users have been reporting performance issues with storage speed for months and it’s finally getting fixed in today’s security update.

Way back in August, some users reported weird a problem where storage drives will experience slow write speeds or even read speeds. Today’s cumulative update (Build 22000.376) addresses it and your HDD or SSD drive’s performance should return to Windows 10 level.

As per reports, Windows 11 has been impacting write speeds by as much as 55 percent, which could significantly slow down machines in some cases. The issue was first flagged during the public testing, but it seems to have somehow slipped through the gaps to also appear in the production or stable builds.

Windows 11 storage drive write speed

As you can see in the above screenshot of a benchmark report, Windows 10 and Windows 11 SSDs writing is noticeable slower after upgrading to the new operating system. In rare cases, users also observed slower read access times in Windows 11.

Windows 11 KB5007262 changelog recently confirmed that a feature called “NTFS USN journal” is causing these issues. Thankfully, the NTFS USN journal is enabled only on is always enabled on the OS drive, so performance issues will be noticeable only when you perform actions with the OS drive.

We can confirm that Windows 10 KB5008215 has fixed issues that could reduce the write/read speed of your storage drives.

Microsoft has also made changes to improve the animation of taskbar icons and volume control of Bluetooth audio devices.

Unfortunately, Windows 11’s highly-requested taskbar drag-and-drop feature is not included in the update. However, the tech giant has fixed an issue that causes flickering when you hover over icons on the taskbar.
