This PowerShell script automatically sets a random image from a user-specified folder as the Windows lock screen wallpaper. It uses modern Windows Runtime APIs for robust performance and does not require administrator privileges.

• No Admin Rights Needed: Runs safely under a standard user account.
• Random Image Selection: Automatically picks a random image (.jpg, .jpeg, .png) from your chosen folder.
• Detailed Logging: Creates a log file (LockScreen_Log.txt) in your Documents folder. This file records every step of the process, making it easy to troubleshoot any issues.
• Path Validation: Checks if the specified image folder exists before attempting to read from it.
