🌙 Enable Dark Mode

Intune Platform Script · Forces system-wide dark mode via registry for the logged-on user

Writes to HKCU — must run as the logged-on user. Takes effect immediately; no reboot needed. Won't apply to new user accounts until they log in and the script runs again (assign to user groups, not device groups).

Script

✦

Set dark mode for apps and system shell registry

Two keys: one flips apps, one flips the taskbar/Start/shell. Both need to be 0 for full dark.

# Enable system-wide dark mode
$path = "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize"
Set-ItemProperty -Path $path -Name "AppsUseLightTheme"   -Value 0 -Type DWord -Force
Set-ItemProperty -Path $path -Name "SystemUsesLightTheme" -Value 0 -Type DWord -Force
