AS you know, Windows devices configuration with Intune is done by using Configuration Profile.
For Windows, 2 profile types are available:
- Settings Catalog
- Templates
Well, you need to prepare for the retirement of the Templates type starting the 2412 service release, scheduled for December.
Starting this release, you will not be able to create new Templates type based configuration profile.
Existing profiles will continue to be available and manageable (edit or deletion), until their migration to the unified settings platform is completed.
