This is fairly simple, but useful. You can create an alarm clock with Windows Media Player in scheduled tasks (Task Scheduler) by programming the following into the Task Scheduler: Step 1: Launch Task Scheduler Code: Start Search Task Scheduler OR Code: Start Key +R Run... taskschd.msc /s Step 2: Create the Scheduled TaskRight-Click on "Task Scheduler Library" and "Create Basic Task..."Name: Windows Media Player Alarm ClockDescription: Wake the hell up!Hit next..."When do you want this task to start?" Choose Daily.Choose your time to wake up on the Daily trigger tabOn the Action tab select "Start a program"Program/script is: "%ProgramFiles(x86)%\Windows Media Player\wmplayer.exe" (Keep the " ")Step 3: Configure Additional Arguments and Set your Sound/Music File IMPORTANT: Add additional arguments This is where you choose your music file to play. Example: "X:\Music\Linkin Park\Hybrid Theory [Bonus CD] Disc 1\02 One Step Closer.mp3" Again, use " " before and after the file path Step 4: Configure the Additional Settings When this is all done, re-open the properties of this task... Under "General" tab, set the following:Turn on "Run whether user is logged on or not""Run with highest privileges"Select Configure for: Windows 7, Windows Server 2008 R2Under the Conditions tab, set the following:Wake the computer to run this taskUncheck "Start the computer only if this computer is on AC power"Under the Settings tab, set the following:Run task as soon as possible after a scheduled start is missedPress OK and you will be prompted for the password for your account. This is in case you are not logged in, it will still try to start Media Player. Step 5: Finalize your Alarm Clock Configuration: Now, from the Task Scheduler Library, look for your newly created task "Windows Media Player Alarm Clock", right click it, and hit Run. It should now work. BUT, before you close WMP, set the volume to its highest levels possible, and set the repeat button to ON. Set your speakers physically to their highest setting, and you will have the loudest alarm clock possible. Let me know if this works for you! Update: Here is a copy of the XML file which you can import into Task Scheduler, but you will have to change the computer name and username to fit your computer as well as the path to your music file. Follow the instructions diligently and it should work for you.
