Which registry key sets the Device Manager rescan rate?

The Device Manager rescan rate can be set by modifying the registry key at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PlugPlay\Parameters. Specifically, the value to adjust is RescanInterval, which determines how frequently the system checks for changes in hardware devices. Adjusting this value can help manage how quickly the Device Manager detects new devices or changes in the system. Always back up the registry before making changes to avoid potential issues.
