Cancel All Running Workflows For All List Items/ Documents In A List/ Library

This PowerShell script will cancel all the running workflows for all the items/documents in a SharePoint List/Library.

There may be some scenario where we need to cancel all the running workflows for a List/Library. In that case we can use the following PowerShell script to achieve it.

#Provide the Site collection url
$web = Get-SPWeb "http://shareserver.com/sitecollection";
$web.AllowUnsafeUpdates = $true;

#Provide the List or Library name
$list = $web.Lists["SD"];
$count = 0

#Loop through all Items in List/Library
foreach ($listItem in $list.Items)
{
    #Loop through all Workflows on each List Items/Documents.
        foreach ($workflow in $listItem.Workflows)
    {
        #Ignore Completed Workflows
        if(($listItem.Workflows | where
        {$_.InternalState -ne "Completed"}) -ne $null)
        {

            #Cancel Workflows
            [Microsoft.SharePoint.Workflow.SPWorkflowManager]::
                    CancelWorkflow($workflow);
            write-output "Workflow cancelled for :
                    " $listItem.Title;
        }
    }
}
$web.Dispose();
