Confirm the policy is working correctly by testing the RDP client behavior on a target device. This verification ensures users can no longer save credentials as intended.
On a device that has received the policy (check Device status to confirm), open the Remote Desktop Connection client by running:
mstsc.exe
In the Remote Desktop Connection window, enter any server name or IP address in the "Computer" field. Before clicking Connect, look for the "Allow me to save credentials" checkbox.
The checkbox should be grayed out and unchecked, preventing users from saving their credentials. This confirms the policy is active.
You can also verify the registry setting directly by opening Registry Editor and navigating to:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services
Look for the DisablePasswordSaving DWORD value, which should be set to 1.
Pro tip: Test this on a few different devices and with different user accounts to ensure consistent behavior across your environment. Document the expected behavior for your help desk team.
Verification: The "Allow me to save credentials" checkbox should be grayed out in mstsc.exe, and the registry value should show DisablePasswordSaving = 1.
