After installing Windows 10 feature update v1809, the screen brightness gets reset to 50% after every shutdown or restart. This seems to be yet another bug<\/a> in the 1809 update.<\/p>\n

This post tells you how to fix\/workaround the screen brightness reset problem in your Windows 10 1809 computer.<\/p>\n

[Fix] Brightness Resets to 50% After Restarting Windows 10<\/h2>\n

Option 1<\/h4>\n

First, visit the motherboard or display driver manufacturer’s website and get the latest driver update from there. See if installing the latest drivers fixes the problem.<\/p>\n

Option 2<\/h4>\n

Another option would be to disable the\u00a0DisplayEnhancementService<\/code> via services console. Right-click Start, click Run. Type\u00a0services.msc<\/code>\u00a0and press ENTER. Double-click the\u00a0DisplayEnhancementService<\/code>service and set it to Disabled.. Restart Windows 10.<\/p>\n

Brightness will stay at 100%. However, this will not let you set it at any other setting (50%,75% etc).<\/p>\n

Option 3<\/h4>\n

If none of the above workarounds help, use this little PowerShell command as a workaround. This command-line resets the brightness level to 100%.<\/p>\n

powershell.exe \"(Get-WmiObject -Namespace root\/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1,100)\"<\/pre>\n
Credits: PowerShell cmdlet & Task Scheduler idea by Evaque<\/a><\/em><\/p>\n
The above PowerShell cmdlet can be used via Task Scheduler to automatically adjust\/set the brightness level at every startup.<\/p>\n
    \n
  1. Right-click Start, click Run. Type taskschd.msc<\/code> and click OK.<\/li>\n
  2. Click on the “Create Task” link in the right pane.<\/li>\n
  3. Assign a task name, say ScreenBrightness<\/code><\/li>\n
  4. Enable “Run whether user is logged on or not”<\/li>\n
  5. Enable “Run with highest privileges”<\/li>\n
  6. Select the “Triggers” tab, and click “New”<\/li>\n
  7. Choose “Begin the task: “At Startup”, and click OK.<\/li>\n
  8. Select the “Actions” tab, and click New<\/li>\n
  9. Paste the command into the Program\/Script Line\n
    powershell.exe \"(Get-WmiObject -Namespace root\/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1,100)\"<\/pre>\n<\/li>\n
  10. Click Ok, and then click Yes when you see this prompt
    \n\"powershell
    \nAfter you click Yes, the arguments part will be split and entered into the appropriate text box automatically.
    \n\"powershell<\/li>\n
  11. Enter your Windows login password when prompted.<\/li>\n
  12. Close Task Scheduler.<\/li>\n<\/ol>\n
    That’s it! When you restart Windows, the screen brightness will change to 100% (1,100).\u00a0You can use this workaround until Microsoft addresses\/fixes the screen brightness resetting problem in a future Windows 10 Cumulative Update.<\/p>\n","protected":false},"excerpt":{"rendered":"
