Is it normal for the Windows Driver Foundation process to take 35% of the CPU when using your USB-C 4K docking station (UD-ULTC4K) while running 2 external 4K displays in Windows 10? I have a Dell XPS 13 9360 which is a fairly powerful laptop but it slows to a crawl when I use the dock now. It seemed to work better before upgrading Windows 10 10.0.17134.48 last week from the previous version. Re: Windows Driver Foundation Service It sounds like either you've turned off some essential Windows Service and/or the chipset driver is missing or corrupted. The sm bus controller is part of the chipset driver, and the others are probably also part of the chipset.
