KB5033372 Brings Copilot To Windows 10

Patch Tuesday Windows 10Patch Tuesday Windows 10

As part of the Patch Tuesday updates, Microsoft has released KB5033372 for Windows 10 versions 21H2 and 22H2. The highlight of this update is that it brings the Windows Copilot to Windows 10, which has only been available in Windows 11 up until now.

Windows Copilot is an AI-enabled Windows assistant that is not only useful in fetching results from the internet but is also smart enough to perform OS-specific tasks, like adjusting the brightness.

Installing this update upgrades the operating system build to 19044.3803 (21H2) and 19045.3803 (22H2).

This update also includes security improvements, and therefore, it is recommended that you install it right away, using either the direct download links provided below or through the Windows Update.

Additionally, Microsoft warns the users that there will be no optional non-security updates for December because of the holiday season.

KB5033372 changelog

This update includes all the improvements that were introduced in KB5032278, which was released on 30th November 2023, and was a Type D update. Therefore, if you already installed that, KB5033372 will be a small update package.

We have compiled and listed all of the new features and improvements in KB5033372 here for you:

  • This update adds the Copilot in Windows button to the right side of the taskbar. This only applies to devices that run Home or Pro editions (non-managed business devices). This is available to a small audience initially and deploys more broadly in the months that follow.
  • The news & interests feature on your device is now larger.
  • If you use Home or Pro consumer devices or non-managed business devices, you can get some of the newest experiences as soon as they are ready. To do so, go to Settings > Update & Security > Windows Update, and toggle the slider in front of “Get the latest updates as soon as they are available ” into the On position.
  • This update addresses an issue that causes IE mode to stop responding. This occurs when you have multiple IE mode tabs open.
  • This update addresses an issue that affects the cursor. Its movement lags in some screen capture scenarios.
  • This update addresses an issue that affects the touch keyboard . It might not appear during the out-of-box experience (OOBE).
  • This update adds new functionality that affects app defaults.
  • This update adds Windows Update opt-in notifications to the screen when you sign in.
  • This update affects the Netherlands time zone. It adds the recent man-made landmass outside of Rotterdam to the shape files.
  • This update addresses an issue that affects the Trusted Sites Zone logon policy. You cannot manage it using Mobile Device Management (MDM).
  • This update addresses an issue that causes IE mode to stop responding. This occurs if you press the left arrow key when an empty text box has the focus and caret (cursor) browsing is on.
  • This update addresses an issue that affects IE mode. A webpage stops working as expected when there is an open modal dialog.
  • This update addresses app cursor issues. These issues occur when apps use the WebView2Standalone XAML control.
  • This update addresses an issue that affects fontdrvhost.exe. It stops responding when you use Compact Font Format version 2 (CFF2) fonts.
  • This update addresses an issue that affects non-admin processes. The game performance goes down, and the video stutters.
  • This update addresses an issue that affects protected content. It stops cross-process windows from being created. Because of this update, you can keep using out-of-process hosting for things like WebView2 under protected, top-level windows.
  • This update affects Microsoft Defender for Endpoint (MDE). It enables Conditional Access (CA) scenarios.
  • This update addresses a localization issue for Great Britain English (EN-GB) locales. The error message for invalid characters in a new Windows Hello PIN is wrong.
  • This update addresses a leak in volatile notifications. This might stop you from signing in to your machine.
  • This update addresses an issue that affects Windows LAPS. Its PasswordExpirationProtectionEnabled policy fails to turn on the setting.

With these fixes and improvements, Microsoft has also disclosed a few known issues with this release.

Known issues

The following list of issues currently exist with this update:

  • Require Device Encryption 65000 error in BitLocker Configuration Service Provider (CSP)

    This issue might be a headache for the IT admins who may have installed KB5031455.

    If you have configured the FixedDrivesEncryptionType or the SystemDrivesEncryptionType policy to “Enabled” in the BitLocker CSP node in the Mobile Device Management (MDM), then the “Require Device Encryption” settings page on some devices may incorrectly show a “65000” error.

    Affected environments are those with the “Enforce drive encryption type on operating system drives” or “Enforce drive encryption on fixed drives” policies set to Enabled and selecting either “full encryption” or “used space only“. Microsoft Intune is affected by this issue but third-party MDMs might also be affected.

    Microsoft suggests setting the “Enforce drive encryption type on operating system drives” or “Enforce drive encryption on fixed drives” policies to “Not configured” to mitigate this issue temporarily, while they work on a permanent fix.

  • Icon alignment issues with Copilot

    When you open Windows Copilot, the desktop icons get randomly rearranged with no sorting order and spread across the screen. This issue only occurs with systems in a multimonitor setup. You can take solace in the fact that the icons are reverted to their original places when you close Copilot.

    At the moment, there is no workaround for this issue. However, Microsoft has disabled Copilot in Preview on devices that have been using a multi-monitor configuration.

  • Copilot will not work if the taskbar is positioned vertically

    If you have moved the taskbar to the left or the right side of the screen and is now in a vertical position, Copilot will be inaccessible.

    At the moment, the only workaround for this issue is moving the taskbar to a horizontal position, which is either at the top of the screen or the bottom.
