    Sadly, the Powershell method does not work on Windows 10 OS build 19043.1237, v21H1.

    I get the following error:

    Get-WmiObject : Not supported
    At line:1 char:2

    This would be very useful for me if I can get it working.

    Using the Function key with Delete and Backspace is the easiest, it can be done without looking at the keyboard – unlike trying to find the brightness keys in the long row of function keys. Sadly this Function key method is not available on the Surface Pro X.

    I have windows 10 with an exterior monitor. I could not find a brightness setting to change to save my life. So my retinas burned for 30 minutes while I tried all the suggested routes, none worked. I have the Intel HD graphics driver which is supposedly the most up to date one.
