+# unactivated  Windows installations. 
+#
+# Usage:
+#   To switch to dark mode, run: .\theme.ps1 -Mode dark
+#   To switch to light mode, run: .\theme.ps1 -Mode light
+#
+#   Optional: Restart the explorer.exe process: 
+#             "Stop-Process -Name explorer -Force; Start-Sleep -Seconds 2; Start-Process explorer"
