The Out-GridView cmdlet allows you to present the results from PowerShell in a sortable and filterable grid, sort of like the 'Out to Grid' results you're used to in SQL Server Management Studio (SSMS), but better! When you add the -PassThru parameter, it allows you to multi-select rows in the grid, and when you click the 'OK' button it will send only the rows you selected down the pipeline to the next command in the sequence to be processed.
