KB5023773 is an optional update and users should only download it if they need these bug fixes. While the optional update is much more secure than the preview builds offered to users in the Windows Insider Program, it’s generally a good idea to wait for the mandatory Patch Tuesday updates.

There are several bug fixes in this update. For example, Microsoft has fixed an issue that affects the ms-appinstaller URI. It now supports the DesktopAppInstaller policy.
The update addresses an issue with the Remote Procedure Call Service (rpcss.exe). The issue may cause a conflict between the Distributed Component Object Model (DCOM) and the Microsoft Remote Procedure Call (RPC) endpoint mapper.
Microsoft has fixed an issue affecting the Microsoft HTML Application Host (HTA). This issue prevents code from running that uses Microsoft HTA. This occurs when you enable Windows Defender Application Control (WDAC) User Mode Code Integrity (UMCI) enforced mode.
Here’s a list of all major bug fixes and improvements:
- The update resolves an issue that affects the desired state configuration. It resets the previously configured options. This happens if metaconfig.mof is missing.
- Microsoft has fixed an issue affecting some printers. A bug affecting printers using Windows Graphical Device Interface (GDI) has been resolved. However, these drivers do not follow the specifications in GDI.
- The update addresses an issue with the Simple Certificate Enrollment Protocol (SCEP) certificate. The system incorrectly reports some SCEP certificate installations as failed. Instead, the system should report them as pending.
- Microsoft has fixed an issue affecting the Fast Identity Online 2.0 (FIDO2) PIN reference icon. It is not displayed on the credentials screen of an external monitor. This happens when that monitor is connected to a closed laptop.
In related news, users recently reported issues with the Windows 10 March 2023 Update, with some noting that the update crashes their devices with a blue screen. You may encounter similar issues when installing the optional update. Therefore, it may be a good idea to wait until the April 2023 updates are available.
