When client computers check in with the WSUS server, you can use the WSUS reporting feature to determine if updates have been deployed. By default, client computers check in with WSUS every 22 hours, but this is configurable. For more information about configuring the time when client computers check in with WSUS, see the "Automatic Update detection frequency" section in Configure Automatic Updates by Using Group Policy later in this guide.
To check the Status of Updates report
On the WSUS console toolbar, click Reports.
On the Reports page, click Status of Updates.
If you want to filter the list of displayed updates, under View, select the criteria you want to use, and then click Apply.
If you want to see the status of an update by computer group and then by computer, expand the view of the update as necessary.
If you want to print the Status of Updates report, under Tasks, click Print report.
