Lattitude E5250 Backlit Keyboard Help?

I want to be able to Keep the Backlight on all the time, I did some searches and found the answer to my problem. The backlit keyboard could be adjusted by the "Customized by Dell Inc. Box Which showed under the "Windows Mobility Box" To get these Dell functions,  the latest "Dell Quickset Utility" Win10 can be downloaded. I tried to download it. It says not compatible with my Lattitude E5250. are there  any other alternative's  ??????

Cheers
