Office Web Apps Server 2013 and Office Online Server 2016 Updates and versions

As usual, if I spent too much time figuring something out, I post it here.  Partially to document for myself for next time, and partially to help the community.   Today, I was working on a customer with an OWAS server and wanted to determine the last OWAS patches deployed and patch it to the current version.  So I checked the add/remove programs and the version listed there was the RTM, and when showing updates, it showed me KB articles, but no version numbers.

There are several partial lists out there - here is a shoutout to a few sources of info:

• Good: http://blogs.technet.com/b/office_web_apps_server_2013_support_blog/archive/2014/06/05/how-to-ensure-you-39-re-using-the-patched-version-of-sp1-for-office-web-apps-server-2013.aspx
• Better: http://blogs.technet.com/b/steve_chen/archive/2013/03/26/3561010.aspx#WAC
• Best:  http://www.wictorwilen.se/WACVersions
• Microsoft:  The best way to find these has been to search the download center and sort by date from newest to oldest: http://www.microsoft.com/en-us/search/DownloadsDrillInResults.aspx?q=office+web+apps+server+2013&cateorder=2_5_1&site=&sortby=-availabledate  

Wictor's blog entry offered up the best tip - How to determine your OWAS version.  Quite simply, look at HTTP headers, and here's the simple one-liner:

(Invoke-WebRequest https://server.fqdn.com/m/met/participant.svc/jsonAnonymous/BroadcastPing).Headers["X-OfficeVersion"]

I've made a tiny script available here to prompt you for OWAS FQDN and check your version up in the Technet Gallery.

This will output the version nice and clearly.  You can see here that I have 15.0.4693.1000 installed (and that is not on any of the previously linked lists)  This is the January 20th 2015 update posted here.  And please be sure to follow the Microsoft documentation on applying patches!


Wictor also has this GREAT post on patching - recommend following this!  In the interest of trying to keep this information up to date, I will build on Wictor's list and update with any that people comment.   Please comment with the link to download as well as the version reported and I will update this list!
