WSUS 3.0 - Report showing success rates of workstation patches,

anything guys?

See if this help - After 24 hours, you can use the WSUS reporting feature to determine whether the updates have been deployed to the computers. To check the status of an update section (on "Update Status Summary report") from below

For accessing reporting feature of WSUS, you are required to install report viewer from Microsoft, not sure they have changed though as it is based on .net still @ http://www.microsoft.com/downloads/details.aspx?FamilyID=a941c6b2-64dd-4d03-9ca7-4017a0d164fd&displaylang=en

thanks for you response, however, I don't believe (based on articles I've been reading) that the report I'm wanting to produce for our client in possible using the native built in reporting in WSUS
probably a 3rd party tool or PowerShell could get me close,
I need a report summary showing a pie chart of how compliant all our workstations are, makes sense?

In forum, it shared that if you have Office Web Components installed on the reporting point, you can modify our reports to create those management graphs

This one used the script to crawl out the compliance check against update if you are interested

then probably I suggest Solarwinds which has quite nice reporting stats which is useful for overall summary awareness http://www.solarwinds.com/patch-manager.aspx
OR Nessus is another candidate http://www.tenable.com/sc-dashboards/wsus-monitoring

sorry, none of these suggestion helped me,
