Disposes of objects in the provided assignment collection.

Stop-SPAssignment [[-SemiGlobal] <SPAssignmentCollection>] [-AssignmentCollection <SPAssignmentCollection>] [-Global <SwitchParameter>]

The Stop-SPAssignment cmdlet disposes of objects in the provided assignment collection. Use the Global parameter to dispose of all objects in the global assignment collector and to stop the global store from collecting additional objects. Provide a SemiGlobal assignment collector to dispose of all contained objects.


Parameter Required Type Description




Provides the assignment collector from which to dispose of objects.




Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.




Stops the global assignment collector from storing objects, and disposes of any objects contained by the global assignment collector.


Error Description


Exceptions Description


Start-SPAssignment -global
$w = Get-SPWeb http://MyWeb
$w | Set-SPWeb -title "Accounting"
Stop-SPAssignment -global

This example uses simple assignment. While easier to use simple assignment, running commands that iterate through multiple SPSite or SPWeb objects while simple assignment is enabled is not recommended. Ensure that Stop-SPAssignment is run before attempting any iterations of multiple objects.
