An install of Windows 11 from MSFT-provided media on an HP desktop PC earlier this year resulted in a ton of HP driver-related crapware on the PC. Windows Update will happily download drivers and user-mode software the driver manufacturer flags as being related.

There is a Group Policy setting under Computer Configuration / Administrative Templates / System / Device Installation / "Prevent automatic download of applications associated with device metadata" that seems to curb most of it, thought I still ended up with a user mode app related to the audio driver.
