Since 2025 came out after the planned release for ZCM 24.4, it is not in the OS Targets and not officially supported.

It will fail to register with an -21 error.

I did create a Dev Ticket to get support added.

--

I have not yet made an OSTarget to allow it to register.

I "SUSPEC"T it will work just fine on once registered with a 24.4 agent as it should be highly similar to Win 11 24H2.

Custom_Ostargets.xml CAN still be used and created, though Server Side patches now often add the support w/o the need for that.

There WAS a defect in the On-line Docs around the process of creating the customer_ostargets.xml.....Somewhere along the lines, one command was missed.  I'm not sure if its been added back....

If I get a chance...I will try and work up something....while also crossing my fingers dev moves quickly on official support....

I might suggest an SR if you possibly can...then it can be associated with the current Dev ticket...

The more folks that proactively ask for it...the higher the priority..

If you honestly care about Windows 2025 Support in the VERY NEAR TERM...try making a ticket and ask to reference OCTIM40D827083

Otherwise, support will no doubt be added but possibly with a lesser priority versus over other issues...
