I just installed the latest Win10 Feature update and now I can't change the screen brightness. I have a Thinkpad SL510. Any Ideas.?

This is just a stab in the dark, but try disabling Adaptive Brightness in the Advanced Power settings.
Since that is an older laptop, Lenovo has moved it to its End of Life Portal, so no new driver or BIOS updates will likely be made for it, so hopefully the Display settings will work for you.
Best of luck,
