Error Name: DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS
You’ve got an unusual Blue Screen of Death, and the name is quite a mouthful: “Driver Unloaded Without Cancelling Pending Operations.” This means that there are operations running on your PC when a driver stops working, causing a major conflict, and thus, a blue screen of death.
This error seems to appear a lot when running an operating system inside a virtual environment, such as VirtualBox, OracleVM, or when running Windows in a non-standard environment, such as through Bootcamp, which relies on BIOS emulation. If you’re running a virtual OS inside another version of Windows, or you’re dual-booting Windows 8.1 on your Mac, there’s a chance you’ll run into this Blue Screen.
This Blue Screen also seems to happen mostly on Intel-based systems (like all modern Macs and about half of all PCs) rather than AMD-based systems.
There are several solutions to the DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS issue, depending on the environment in which it occurs.
Be sure all your drivers are updated, especially important system drivers and video drivers. If Windows Update doesn’t find anything and you’re still getting the issue, try our own Driver Reviver for a more thorough update.
Be sure your virtual software (such as VirtualBox) or BootCamp is updated to the latest version. This has the effect of removing a lot of crash bugs such as this one.
If the problem persists, you may need to try another approach to getting your favorite OS on your machine. Good luck!
