I have a Windows Server 2012 R2 server with a 100 GB virtual drive for the WSUS data that has been running fine for 2 years and just recently some change caused the drive to run out of space. I don't know enough about what changed to cause a sudden increase in data to fill the drive, so I don't know whether I should try to fix the problem or just stop the service, erase the data and rebuild the update server.
The network only has about 30 Windows 7 64 bit clients, Microsoft Office 2016 32 bit and Microsoft Security Essentials to be updated besides the server itself. I believe it was all up to date through August, but I'm not positive. I also understand that Microsoft has changed the way they issue updates for Windows 7 and now issue a single roll-up update each month instead of a bunch of individual updates. So I am leaning towards rebuilding the WSUS and would like to have a step by step guide on how to stop and remove the existing service and data and how to reinstall or rebuild it.
I would appreciate some guidance on where to start and how to proceed.
Thank you in advance for anybody willing to help me out.
