Download this document as a pdf file

With the release of Windows 8, and continuing with Windows 10, Microsoft imposed many restrictions on what it will let you install. The casualties include legitimate USB device drivers. To use the majority of USB data acquisition devices you now need to disable Windows driver enforcement before installing your USB drivers.

If you have upgraded to Windows 8 or Windows 10, and Windows is not recognising your USB instruments, go to Device Manager and remove the device there (Section 1) before proceeding as in Sections 2 and 3 below.


1. When upgrading to Windows 8 or 10: Remove the USB Drivers

Windows Tools or Power User Menu
  1. Open Device Manager. You can do this via the Windows Power User Menu, which is also known as the Windows Tools Menu. To access this, on your keyboard press the Windows and X keys simultaneously. Alternatively you can right-click the Start menu.
  2. In Device Manager, under "Other Devices", you will see your USB data acquisition hardware with a yellow warning sign. Right click the device and choose Uninstall. You will be asked to confirm that you want to do this.

You can now follow the next sections to re-install your drivers.


2. Disable Windows Driver Signature Enforcement

This involves restarting your computer three times. Make sure then that you have closed any open programs before proceeding.

  1. Tell Windows you are about to temporarily change your computer settings.
    1. In Windows 10, click the Start button and select Settings.
      In Windows 8, move your mouse to the bottom right of your screen. Select the Settings gear and choose Change PC Settings.
