All the EIOBoard interfaces work on both Windows 10 and Windows 11, but there are some things to keep in mind with the licensing.
Upgrading the OS to Windows 11 will delete the install key to license the application, so make sure you have the install key saved to be able to re-enter it after upgrading. You will also want to make sure to uninstall kiosk application or contact EIOBoard support first so that slot for the install key is freed up. Your settings will be saved in the registry so you will be good to reinstall the application and relicense it after upgrading to Windows 11.
If you need any help relicensing your kiosk or mustering tablet after upgrading to Windows 11, feel free to contact support at email@example.com
