Parameters

1

ParameterRequiredTypeDescription
WebTrueSPWebPipeBind

Specifies the URL or GUID of the Web containing the theme to reset.

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; a valid name of Microsoft SharePoint Foundation 2010 Web site (for example, MySPSite1); or an instance of a valid SPWeb object.

SetSubWebsToInheritFalseSwitchParameter

If specified, all child webs will be reset to inherit the theme of the specified web or root web.

AssignmentCollectionFalseSPAssignmentCollection

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.

2
