Board Software
The driver disk included with the ASRock X570 Taichi is pretty standard-fare, split into four categories and an ads page. ASRock has included some bloatware, but the "install all" list can be trimmed. If you don't want the extra software, click on "install all" for a new window that lets you weed out unwanted items. I would like to see this simplified in the future, with the initial list including the check boxes to trim the install list.
For utilities, ASRock has kept it very minimal. There is App Shop, which offers a wide range of software, as well as a Live Update feature for drivers.
Also included are the "Restart to UEFI" applet, which is very handy for booting straight into the BIOS, and ASRock Polychrome RGB, which is a pretty thorough RGB control app.
