WSUS Contents on CM 2012R2

Question

We have been running CM 2012 R2 - CU2 for about 8 months and over the last 30 or so days, my WSUSContents is 70G which is almost 50% of my total drive space.  I have doubled checked everything I can think, WSUS is being configured via SCCM site
SUP settings. what can I do to fix this!
I have 2 Seconday Servers, both have SUP, installed and configured via CM, these servers only have a couple of Gigs of usage for the WSUS.
I do monthly Cleanup within the WSUS console!

Answer 1

Cam in to the office after the new year, my Content store is now over 120Gigs.  It consist of Alpha Numaric Folders 00 though FF, the contents of each folder is a series of files that appear to be GUID based in name with .CAB, .EXE, .TXT.  On investigation
of a few of the TXT files, all appear to be some form of Microsoft update, the few I check consited of updates for IE 11, and Silverlight.
Just so I'm clear, my Configmanager install is supposed to be managing this, and this was working well untill a few weeks ago, nothing has changed other then MS patches.  The WSUS cleanup Wizard completes with no Errors, and gives a status of;
unused updates deleted: 0
unused update revisions deleted: 0
Computers that ahve not Contacted the server Deleted: 0
Diskpace Freed by Deleteing unused content files: 0mb
Decliend expired updates: 0
Declined Superseded updates: 0
this is what I would expect, I guess I'm going to pull the SUP from Configmanager, effectivly uninstalling WSUS, I'll Manually delete the Content and start over, but I am worried that shit is going to cause bigger issues.  not to mention my updates
will need to be re-deployed!
