I assume that your are familiar with the Task Scheduler in Windows, so this one should be a quick one:

1. Create a new task
2. Create an Action

3. Program/Script: <pre class="lang:default decode:true ">powershell.exe</pre>

4. Add arguments: <pre class="lang:default decode:true ">-NoProfile -ExecutionPolicy Bypass C:\path_to_your_script.ps1</pre>

5. Set all the other needed things liker any other scheduled task
6.  Have an automated powershell script, easy right?
