Surface pro 3 Brightness control missing

I should add how I thought I shut off Automatic updates.   I turned off the options in the interfaces for Updates.   I went into services, and stopped the service(s).  Then I moved the update services (as an Administrator)  from either Auto or Manual to  "Disabled".   

I suspect most normal person would conclude that changing the configuration and disabling the Auto-Update Services would prevent updates.  

I can only conclude that one of the following is true:

1. My Surface applied some hotfix or roll-up (somehow, despite disabled auto-updates); OrT
2. There is one more auto-update setting I missed; or,
3. The bug is native to the older version and asserts itself at some point with 48 hours of a clean install to a particular old Win10 Version. 

I've already invested way too much time in trying to solve this issue, so I'm raising the white flag... and surrendering.  My surface will make a great docked Home Theater for one of our TV's (as an external monitor).

Again the same old issue. After the last windows update (version 1903 build  18362. 239) i cant adjust the screen brightness ( is set in 100% and it is draining the battery).

This is the second time an Windows actualization creates this issue.

Does anyone have a clue how to fix it this time?

Thank you

Such a shame that a large company who created both the HARDWARE and SOFTWARE can't make this work. 

Is that why people start buying Macbooks?

Back to Win8.1... better than nothing.

I will follow this thread... Maybe one day it will be solved, or, maybe will have some cash to buy a Mac.
