This issue cropped up immediately after Windows Update installed two definition updates for Windows Defender consecutively. Windows Update started offering definition 1.193.3002.0 after the definition updates were installed, which was unexpected as a later
version was installed through the updates. After installing 1.193.3002.0, Windows Update offered update 1.193.3192.0, and started offering 1.193.3002.0 immediately after installing 1.193.3192.0. I do have a recent system image backup (stored in another partition).
I have tried manually resetting Windows Update (using the instructions I found on Microsoft Support) to no avail. I have restarted my computer multiple times. Both sfc and DISM found no problems with my computer. I downloaded and installed MBAM (free version)
and ran a scan with it, which did not turn anything up. Should I just restore my computer from my system image backup?
<edit>
the Windows Defender UI indicated that update 1.193.3192.0 is installed. However, Windows Update is still offering (and automatically installing and looping) update 1.193.3002.0

I am running Windows 8.1 64bit with all updates (except for the pesky definition updates thingy) installed. I had a McAfee trial thingy installed quite some time ago, but I uninstalled it and ran MCPR (from the McAfee site) afterwards. I haven't made any
changes to my computer in the past couple of weeks.

Turning Windows Defender off, restarting, and turning it back on did not resolve the problem. Dangit.
