Windows 10 is crashing with CorsairVBusDriver.sys failure after latest update

Windows CorsairVBusDriver error

A new bug in a recent Windows 10 update or a driver update
pushed out via Windows Update is crashing some devices with
CorsairVBusDriver.sys failure. The Blue Screen of Death error
message is “System Thread Exception Not Handled” and it
prevents the system from booting to the desktop.

According to several user reports, Windows 10 has
been going crazy for some users in last one week, with an error
“CorsairVBusDriver.sys” that could potentially leave the
machine stuck in a boot loop.

For those unaware, CorsairVBusDriver is a component shipped
with drivers compiled by Corsair, a hardware company. The
problem with CorsairVBusDriver.sys has apparently been hanging
around for two months, but it became more prevalent last week
Windows 10 December 2020 updates were released.

It’s possible that the problem is linked to this month’s
cumulative update which has already caused other problems for a
lot of people.

Fortunately, a fix for “System Thread Exception Not Handled”
BSOD error caused by CorsairVBusDriver.sys has now been
discovered by some users.

How to fix CorsairVBusDriver.sys error in Windows 10

To fix “System Thread Exception Not Handled” error caused by
“CorsairVBusDriver.sys” error, follow these steps:

  1. Unplug your Corsair devices if you’re using.
  2. Assuming that your computer is not booting correctly, you
    might see ‘Choose an option screen’.
  3. Select Troubleshoot > Advanced options > Command
  4. Command Prompt will start on X:Sources and you need to
    identify your OS drive letter.
  5. To identify your drive name, type “diskpart” without
  6. Wait for the diskpart command to load and then type “list
    vol” without quotes.
  7. A list of your drives should now appear. Identify the drive
    letter that is your OS drive or simply note down all the drive
    letters, so you can try them one by one.
  8. Relaunch another instance of Command Prompt and it will
    start on X:Sources again.
  9. Now you need to enter the drive letter where Windows 10 is
    installed. In our case, it was ‘C’.
  10. Type c: to enter into the drive.
  11. Type dir.
  12. If you see the Windows folder, you’re in the correct drive
    letter. If not, simply close the Command Prompt and launch it
  13. Type the drive letter and then type dir to
    see Windows folder.
  14. Type the following command
    cd windowssystem32drivers
  15. Once you’re in the drivers folder, type the following
    ren corsairvbusdriver.sys corsairvbusdriver.bad
  16. This will rename the driver file and Windows can’t call it
    on boot, but it’ll remain installed on your device.
  17. Close Command Prompt and reboot.

If you followed the steps correctly, Windows 10 will boot to
the desktop again and would need to uninstall Corsair Utility
Engine (CUE) and drivers to prevent the Blue Screen of Death

If you’re unable to boot to the desktop, open Command Prompt
window again and enter into the drive where Windows 10 is
installed, and then follow these steps:

  1. Generate a list of your installed first
    party and third party drivers with the following command:

    dism /image:c: /get-drivers
  2. In the above command, c: would be your OS drive letter.
  3. After entering the get-drivers command, you’ll see a long
    list of drivers with the “Publisher Name” and “Original File
  4. CorsairVBusDriver drivers will carry names like oem18.inf,
    oem19, inf, etc under the original file name section.
  5. If you’re unsure about a particular
    driver, you can type the following command to get more
    information about the driver:

    dism /image:c: /get-driverinfo /driver:oemxx.inf
  6. Type the following command to remove the
    botched Corsair driver:

    dism /image:c: /remove-driver /driver:oemxx.inf
  7. You can also uninstall other Corsair drivers by following
    the above steps.

In all the above commands, ‘C:’ would be the drive letter of
your OS drive. Once done, close the Command Prompt window,
restart your device and it will boot to the desktop again.
