Why GUI Automation Stops When the Remote Desktop Window Is Minimized — Disabling the RDP Client's Render Suppression on the Connecting PC

Running RPA, GUI tests, or Computer Use over Windows Remote Desktop sometimes shows an odd pattern: it works while the Remote Desktop window is visible, but stops the moment it is minimized. One cause is the render suppression the RDP client applies on minimize, and setting RemoteDesktop_SuppressWhenMinimized to 2 on the connecting PC can mitigate it. This post walks through the mechanism, the setting procedure (with the differences between the Microsoft and UiPath docs), how to verify the effect under matched conditions, and the states this setting does not fix (disconnect, lock, logoff, sleep).
