Windows 10: Windows Screen suddenly went dimmer then it normally is. WHY?

My HP ENVY DV7 Laptop Screen suddenly went dimmer then it normally is. IT WAS ALOT BRIGHTER BEFORE

Pango Screen Dimmer | Tray Color | Visually Impaired

I have been using pango screen dimmer
PangoBright screen dimming utility, from Pangolin Laser Systems
with an HP Z23N turned to portrait mode.

Pango is the only app I know of that sits in the tray and allows keystroke control of the brightness levels. The needed settings vary as the daylight and what's on the screen changes. Other dimming solutions do not offer the same control and flexibility, as far as I know. I went over this in detail after an Unbutu update killed an even better solution a couple of years ago. Developers then could not suggest an alternate or any solution. Not long after that I turned to Windows.

Pango worked fine this am.
Now suddenly it will not load. I have downloaded a fresh instance a couple of times. Same story, running as Admin and User.

Additionally
My windows tray has turned to a light color with a fade line running from the center of the tray on the left to a bit short of dead center. See the bottom of the screen print below

I am wondering if a Window 10 update squirreled the app and altered the tray colors?

Any fixes? Alternates?

 

After creator update on windows 10 the screen dimmer function is not working sunglasses needed

• Just to clarify, are you referring to a "screen dimmer" app? No the ordinary computer dimmer
  
• Did you get an error message? No
  
• Were you able to adjust the level of brightness of your computer in Windows Settings? No

Rich.

First I am using the free / home edition of Windows 10 so maybe that is the difference between what you get and what I get?

I took your suggestion and looked at the updates. I am lost but I think the one yesterday may be the source of the killing of my Pango?

I have downloaded your two alternates but not yet installed them.

Could you give me some guidance for a workaround/ reversal?

What might the implications of a reversal?


Thanks for any suggestions.
