Although the client-side Remote Control icon (SMSrc.cpl) is the preferred method for changing client-side Remote Control settings, it is still useful to know where the registry settings for these items are located.
The settings listed in the following table include all the switches that control which Remote Control features are available for a client computer. In nearly all cases, a value of 1 means that the feature is enabled. A value of 0 means that the feature is disabled.

These settings are dynamically polled by the Windows NT Remote Control Agent, but they are not polled by the Windows 95, Windows 98, or Win16 agents. Changes made through the Remote Control icon (SMSrc.cpl) are applied immediately to the running agent. This functionality effectively makes the Windows 95, Windows 98, and Win16 agents just as “smart” as the 32-bit agent, provided that settings are changed through the Remote Control icon, not just simply placed into the registry.
This means that changes made to these registry settings (not the Remote Control icon) will take effect immediately on Windows NT, but on Windows 95 and Win16 clients they will not take effect until you stop and restart the Wuser service.
