Messages about authorization errors in the Admin Service

The Administration Service is a REST API (Representational State Transfer) based on the Open Data (OData) v4 protocol used by Configuration Manager to manage console extensions, Tenant Attach functionality, etc…
In the 2303 release, auditing messages related to authorization errors (previously recorded in the CM logs) have been introduced; these messages are visible in the “All Status Message” view present in the Monitoring section and contain information such as: attempts to access resources, number of attempts for authorized requests made by the user in a day, read operations for HTTPS requests and for cloud-initiated operations.

The supported compatibility levels are: 150, 140, 130, 120, 110.

Software Updates

Unified Update Platform (UUP)

The Unified Update Platform (UUP), released in General Availability (GA), is a method of providing updates to all Windows devices from a single update platform; it also allows you to make operating system updates easier while reducing the size of the package to download and the time to apply. Starting March 28 and with the release of subsequent Cumulative Updates, Windows 11, version 22H2 devices will be able to receive Quality Updates via the Unified Update Platform (UUP).

Revised supersedence time for Software Updates

With the release of the Unified Update Platform (UUP) service in GA, the default value for supersedence of updates is being updated; this value should be greater than 3. For new installations of the Software Update Point role, this value will be increased to 6. Existing Configuration Manager infrastructures will need to be manually adjusted to this value.

New settings for the management of new features introduced through servicing

Within the Software Updates section, available in the Client Settings, a new settings called “Enable Windows features introduced via Windows servicing that are off by default” has been introduced which allows you to control the activation of new features introduced during system servicing windows.

If this setting is set to Enabled, all the features introduced in the last Cumulative Update installed will be activated while, if set to Not Configured or Disabled, these will remain disabled until the Feature Update that includes these features is installed.


Improvements in the Configuration Manager console

In the 2303 release, further improvements were introduced to the console; the most important update is the extension of the dark mode functionality also in the secondary site removal wizard.


Version 2303 of Configuration Manager saw the introduction of new features strictly focused on better management of the update component on Windows 11 systems given the release in General Availability of the Unified Update Platform (UUP) service.
