Policy CSP - ADMX_CtrlAltDel
Tip
This CSP contains ADMX-backed policies which require a special SyncML format to enable or disable. You must specify the data type in the SyncML as <Format>chr</Format>. For details, see Understanding ADMX-backed policies.
The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see CDATA Sections.

./User/Vendor/MSFT/Policy/Config/ADMX_CtrlAltDel/DisableChangePassword
This policy setting prevents users from changing their Windows password on demand.
If you enable this policy setting, the 'Change Password' button on the Windows Security dialog box won't appear when you press Ctrl+Alt+Del.
However, users are still able to change their password when prompted by the system. The system prompts users for a new password when an administrator requires a new password or their password is expiring.

./User/Vendor/MSFT/Policy/Config/ADMX_CtrlAltDel/DisableTaskMgr
This policy setting prevents users from starting Task Manager.

If you enable this policy setting, users won't be able to access Task Manager. If users try to start Task Manager, a message appears explaining that a policy prevents the action.
If you disable or don't configure this policy setting, users can access Task Manager to start and stop programs, monitor the performance of their computers, view and monitor all programs running on their computers, including system services, find the executable names of programs, and change the priority of the process in which programs run.
