If you don’t manually install the updates, Windows will automatically download and schedule them to be installed when you’re not actively using the PC.

This months’ update comes with many improvements, with some of the highlighted ones below:

• New! This update adds a new Game Pass recommendation card on the Settings home page. This home page shows on Home and Pro editions when you sign in to Windows using your Microsoft account. The card appears if you actively play games on your PC.

• New! This update affects File Explorer. You can now create 7-Zip and Tape Archive (TAR) files using the context menu. When you right-click a file, a Compress to item gives you ways to compress a file using tools like gzip, bzip2, and more. There is also a new compression wizard in Additional options. It will help you choose more formats and add details. You can use different types of compression to add many files to archives in other TAR formats. You can also change the compression level and choose the types of data to store in each archive.

• New! This update makes it easier to see when you have selected files or folders in File Explorer. Because of this change, a thin, black border now appears around the item you have selected.

• New!  We are advancing the Copilot experience on Windows. The Copilot app is now pinned to the taskbar and behaves like an app. This gives you the benefits of a typical app experience. For example, you can resize, move, and snap the window. For existing Windows 11 PCs, the timing of availability and delivery method will vary. This might not be available to all users because it will roll out gradually. 

  Important This feature only applies to new Windows 11 PCs and new Copilot+ PCs that ship to the European Economic Area (EEA) and other markets where Copilot is available.

• New! This update improves the Virtual Filtering Platform (VFP) within Windows nodes. Now, VFP has more support for packet drop collection. This will make it easier to troubleshoot issues.

• This update changes the units for DDR speed from MHz to MT/s.

• New!  You can now use OneDrive as a RemoteApp in Azure Virtual Desktop.

Please note that some of these features are being gradually rolled out.

As for known issues, Microsoft says it’s aware of two known issues with this release.

The first affects enterprise users who may have problems upgrading from Windows Pro to a valid Windows Enterprise subscription.
