+                                    The script disables the Windows Spotlight feature. Windows Spotlight is a feature in Windows 10 and Windows 11 [1] that automatically downloads
+                                    and displays random wallpapers on the lock screen [1] [2]. These images are sourced from the internet [1] [2] [3]. At times, it might also promote
+                                    various Microsoft products, services [1] [2], or even third-party apps and content [4].
+
+                                    When the lock screen fetches images from the internet, there's a silent data exchange happening. This can inadvertently reveal details about the
+                                    user's device or their preferences.
+
+                                    To mitigate this potential privacy risk, the script makes a change to a key (`DisableWindowsSpotlightFeatures`) in the Windows operating system [3].
+                                    Originally, Windows Spotlight is turned on unless the user decides otherwise [2].
+                                    By applying this script, users can be sure their lock screen remains private and doesn't retrieve wallpapers from the internet, eliminating potential
+                                    data leaks.
