To follow up on that, is there a technical reason why the on-device Bluetooth must be used if there is another Bluetooth adapter in the system? As an example, my system has Intel Bluetooth built into the motherboard. If Vive Console wasn't insistent that its Bluetooth driver was installed I could sidestep the issue.

That was pretty much the result I've been getting for years. Support kicks the can to another channel which goes basically ignored (here, /r/vive, etc.). I am very disappointed and am unlikely to choose HTC products in the future if this is the kind of support I can expect.

It is normal, since April 2018 update of Windows 10, to have Memory Integrity/Core Isolation enabled on new installs of Windows operating systems. The btwusb.sys driver (mentioned in the OP) provided for HTC Vive and Vive Cosmos headsets prevents this setting from being enabled. HTC has been made aware of this issue countless times since then. Is there a reason why HTC expects me to spend hundreds of dollars for a VR headset and at the same time not provide an updated (read compatible) driver that conforms to the HVCI requirements that have been expected for the past four years? If I were to be infected with malware because of a BYOVD exploit because I was unable to implement the proper security measure will HTC reimburse my losses? I think not. I apologize for the somewhat unreasonable tone in this message, but I am seriously wondering why I must choose between enjoying my HTC VR device or having a secure computer. While I would like to hope that HTC will provide a properly signed driver, I'm not going to hold my breath.
