Powershell 4.0 on Windows 7 and Windows Server 2008 R2

I have installed .Net Framework 4.5.1, and Powershell 4.0, and having some issues with some cmdlets; primarily dealing with scheduled tasks.  Is Get-ScheduledTask available when Powershell 4.0 running on Windows 7 or Windows Server 2008 r2?  I can't seem to find the module to import, and no modules with schedule in their name shows up with running Get-Module -listavailable.

thanks.
