How do I reset all BITS jobs from PowerShell?
In Windows 7, the BITSAdmin command has been deprecated in favor of BITS PowerShell cmdlets. What is the PowerShell equivalent of the command bitsadmin /reset /allusers?
From the available cmdlets and the documentation of them as well as bitsadmin I'd say
Get-BitsTransfer -AllUsers | Remove-BitsTransfer
will do what you want.
