<p>With thousands of updates released from Microsoft your WSUS disk space can get low pretty fast.<br />
To free up some WSUS disk space we can delete superseded updates that are not applicable and thus not needed anymore.</p>
<p>To do this open the WSUS Administration Console and in the right pane add the <strong>supersedence flag</strong> column to All Updates view.</p>

<p>Filter criteria to <strong>Approved</strong> with <strong>Any</strong> status.</p>
<p>Sort the list by <strong>supersedence</strong> flag where all updates that are superseded by another update can be safely removed.<!--more--></p>
<p>Here&#8217;s an explanation of the supersedence icons:</p>
<p><strong>Blue square on top</strong>: this update supersedes another update, therefore we should not remove this updates.<br />
<strong>Blue square in the middle</strong>: this update has been superseded by another update and also superseds another update and it can safely be removed or declined.<br />
<strong>Blue square in the right below corner:</strong> this update has been superseded by another update and it can also be safely removed or declined.<br />
<strong>No supersedence icon</strong>: update does not supersede and it&#8217;s not superseded by another update</p>
<p>After you have declined superseded updates you should run the Server Cleanup Wizard from the Options screen in the left pane.</p>
<p>You can leave all options selected in the wizard screen and run the wizard to delete unneeded files from the WSUS server.</p>
