hello , Yesterday I installed the 1809 update , and today i noticed that each time i restart my laptop the brightness level is being reset automatically to 0% or 25-50 i'm not really sure , and after windows will boot up , i will need to manually adjust the screen brightness again to 100% . I searched the web and i found this https://www.windowscentral.com/windows-10-october-2018-update-common-problems-and-fixes#fix\_brightness\_windows10\_1809 , and it might be an update issue i think , by the way , my power plan is set to maximum performance and my laptop is always plugged in , and solutions or ?

There is a solution which worked for me..I had an Intel HD 620 graphic card ..I tried updating this driver from windows device manager but it said this is the updated driver.
What I did is I went to the Intel website and found the latest driver and installed it..Which works without any issues..Once i Installed it I had no issues

I have the same intel graphics card ( 620 ) and also a nvidia 940mx gpu .
Try updating your Intel driver using this link https://downloadcenter.intel.com/download/28289/Intel-Graphics-Driver-for-Windows-10?product=80939
I did not have issues after updating it..Generally the brightness issue occurs when your PC/laptop goes to sleep..so I actually increased my sleep time and closing the lid options so that my laptop does not go to sleep.
After updating the driver I changes these settings to default values.Everything works fine now
I updated to the latest Intel driver (version 25.20.100.6373 for the UHD 620 graphics) and my brightness still drops to 50% after a reboot.
