Q1
Why does the BIOSTAR MSFT Icon appear in the lower right corner when using BIOSTAR Intel or AMD 800 Series motherboards?

If the motherboard has LED control functions, Windows 10/11 will automatically install the BIOSTAR MSFT 6K7322 driver, which is recognized as a USB hot-plug device. The BIOSTAR MSFT icon will appear in the system tray (lower right corner).



This icon is associated with the lighting control functionality and it can be safely ignored, as it does not require any user action.
