- Print support app (PSA) APIs – Using the PSA framework, printer manufacturers can extend printer functionalities and user experience. For more information, see Print support app design guide.
- PIN-protected printing for IPP and Universal Print - Standard print dialogs now include a user interface to enter a PIN code.

Besides, it update enables the InternetExplorerModeEnableSavePageAs Group Policy.
Finally, it comes with several fixes.
The update KB5014666 resolves the annoying bug with Hotspot, which causes the OS to drop the primary Internet connection once you enable it. Now you can continue using the Mobile Hotspot without issues.
Addresses an issue that affects the Cloud Clipboard service and prevents syncing between machines after a period of inactivity.
- Addresses an issue that prevents the Pashto language from appearing in the language list.
Addresses an issue that affects the touchpad area that responds to a right-click (the right-click zone). For more information, see Right-click zone.
- Addresses an issue that affects some certificates chains to Root Certification Authorities that are members of the Microsoft Root Certification Program. For these certificates, the certificate chain status can be, “This certificate was revoked by its certification authority”.
- Addresses an issue that leads to a false negative when you run scripts while Windows Defender Application Control (WDAC) is turned on. This might generate AppLocker events 8029, 8028, or 8037 to appear in the log when they should not.
- Addresses an issue that prevents the use of Encrypted File System (EFS) files over a Web-based Distributed Authoring and Versioning (WebDAV) connection.
- Addresses an issue that causes a domain controller to incorrectly write Key Distribution Center (KDC) event 21 in the System event log. This occurs when the KDC successfully processes a Kerberos Public Key Cryptography for Initial Authentication (PKINIT) authentication request with a self-signed certificate for key trust scenarios (Windows Hello for Business and Device Authentication).
- Addresses an issue that causes the LocalUsersAndGroups configuration service provider (CSP) policy to fail when you modify the built-in Administrators group. This issue occurs if the local Administrator account isn't specified in the membership list when you perform a replace operation.
- Addresses an issue in which malformed XML inputs might cause an error in DeviceEnroller.exe. This prevents CSPs from being delivered to the device until you restart the device or correct the XML.
- Addresses an issue that causes Microsoft NTLM authentication using an external trust to fail. This issue occurs when a domain controller that contains the January 11, 2022 or later Windows update services the authentication request, is not in a root domain, and does not hold the Global Catalog role. The affected operations might log the following errors:
- The security database has not been started.
- The domain was in the wrong state to perform the security operation.
- 0xc00000dd (STATUS_INVALID_DOMAIN_STATE).
- Addresses an issue that affects devices enrolled in Update Compliance and have installed the April 2022 Windows non-security or later updates. For more information, see Monitor Windows Updates with Update Compliance. Devices that are enrolled in other Windows diagnostic data processor configuration programs or have a combined enrollment with any of these programs and Update Compliance are not affected.
- Addresses a known issue that might prevent you from using the Wi-Fi hotspot feature. When attempting to use the hotspot feature, the host device might lose the connection to the internet after a client device connects.
It is worth mentioning that the same update is available for Windows Server 20H2, which is still supported. But its consumer counterpart has reached EOL.
