Yes - the Anniversary Update.
Your build 10586 is Windows 10 version 1511. The built-in Defender Offline option came in with the AU build, 14393 - Windows 10 version 1607.
But Defender Offline has been available for download since Windows 7...

Follow the instructions for Windows 7 in the above link to make a bootable USB/CD that will run Defender Offline.
Edit: I have tried it and it works equally well under Windows 10 (in fact it came with more up to date definitions than I currently have on my PC).
