@erbanku, thank you! Did you check that they ran merely without errors, or that they actually achieved the desired result?

Anyway, I've transformed them, if of use. This allows them to be invoked via Windows automation software (like Task Scheduler) more easily:

1. Enable-DarkModeApps.PS1

   #!/usr/bin/env -S pwsh
   If ($IsWindows) {
   	If ((Test-Path -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize') -NE $True) { New-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Force -EA SilentlyContinue };
   	New-ItemProperty -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Name 'AppsUseLightTheme' -Value 0 -PropertyType 'DWord' -Force -EA SilentlyContinue;
   }
   

2. Enable-LightModeApps.PS1

   #!/usr/bin/env -S pwsh
   If ($IsWindows) {
   	If ((Test-Path -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize') -NE $True) { New-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Force -EA SilentlyContinue };
   	New-ItemProperty -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Name 'AppsUseLightTheme' -Value 1 -PropertyType 'DWord' -Force -EA SilentlyContinue;
   }

3. Enable-DarkModeSystem.PS1

   #!/usr/bin/env -S pwsh
   If ($IsWindows) {
   	If ((Test-Path -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize') -NE $True) { New-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Force -EA SilentlyContinue };
   	New-ItemProperty -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Name 'SystemUsesLightTheme' -Value 0 -PropertyType 'DWord' -Force -EA SilentlyContinue;
   }

4. Enable-LightModeSystem.PS1

   #!/usr/bin/env -S pwsh
   If ($IsWindows) {
   	If ((Test-Path -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize') -NE $True) { New-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Force -EA SilentlyContinue };
   	New-ItemProperty -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Name 'SystemUsesLightTheme' -Value 1 -PropertyType 'DWord' -Force -EA SilentlyContinue;
   }
