PEAK Hardware Control Panel Applet Version History

Since version 4, the PEAK Hardware Control Panel Applet is a part of our driver setup. It lists available hardware, installed drivers, and APIs. Device IDs and non plug & play hardware can be configured with this tool. After installation you can invoke it via the Windows Control Panel or by entering "PEAKCPL" in the Windows search bar.

Note: As of driver setup version 4.3.0, the PEAK Hardware Control Panel Applet is no longer included. It has been replaced by "PEAK Settings" (see separate version history).
