I have a question that I've been wondering the answer to for some time. For example, let's say a user has a Bluetooth driver present on their system with the name 12345.sys for example purposes, and it's loaded. If the user disables the Bluetooth device in Device Manager, does that unload 12345.sys, and stop it from making calls and/or being called?

I ask because as a kernel debugger, I have read in the past that software must be properly removed from either Control Panel's Add/Remove Programs list (or with a manufacturer removal tool) to unload drivers fully, as disabling the device may not fully unload the driver. I am wondering if this is actually the case.

  • Generally, yes it is the safest and most reliable way. Exceptions could be made, such as malware or poorly written software (Java!) where a good manual registry scrub is needed to clean out the odd bits. May 29 '14 at 0:07
