For users comfortable with command-line interfaces, Windows PowerShell offers a method to adjust brightness without needing activation. This approach utilizes Windows Management Instrumentation (WMI) or specific commands targeting monitor settings.

Here is a basic PowerShell script to set brightness:

“`powershell
$brightness = 50 Set desired brightness percentage (0-100)
(Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1, $brightness)
“`

This script sets the brightness to 50%. You can modify the `$brightness` variable to any value between 0 and 100 to change the brightness accordingly.

Steps to run the script:

  • Open PowerShell with administrative privileges.
  • Copy and paste the script into the PowerShell window.
  • Press Enter to execute.

Note that this method may not work on all hardware configurations, especially on some external monitors or older systems.
