You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

1) Download and install Driver Easy.

2) Run Driver Easy and click Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to a flagged display driver to automatically download and install the correct version of this driver (you can do this with the FREE version). 
Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

Hope you can get rid of the error now.

      Hi, Utkarsh Gaurav. The Error 87 occurred is probably due to the way you enter the command. There is a blank before each /. Try to run the command again in the a correct-enter way.

      • i tried on powershell also with other codes , every things goes fine , test results are good, but still my application is blocked from using graphic hardwares.

        • April Cai

          Did you try to reinstall your display driver?

    I take issue with the statement that this problem is always caused by the Graphics driver….More accurately it always caused by Windows 10 version 1607 (anniversary)….role back to 1511….problem solved.
