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.

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

Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
I tried manually downloading updates and installing them. The looping continues.
However a similar problem I had with Microsoft Windows Malicious Software Removal Tool (?) some time ago relied on running the manual install and running windows update in just the right order before the looping stopped.
For now I have hidden kb2267602 1.193.3002.0.
See "Manually download the latest updates", and read the rest of the web page too. See if manually downloading the "Definitions" breaks the loop?

Did anyone try my earlier suggestion to hide the update?
If you switch off Automatic Updates and set them up to not download and only notify you then it is possible to hide a troublesome update. After doing such a thing you may return to your normal Automatic Update settings.

Hide Windows 7, or 8, Updates that you do not Ever Want to Install

This is the one update that I would hide if it was my decision (as it is the oldest update).
Definition Update for Windows Defender - KB2267602 (Definition 1.193.3002.0)
I am so glad to see all of this,
I have tried to "fix" 4 computers with this problem to no avail
Tired of trying. now I feel I do not have any Https sites that are secure.
I did refresh and it still did nothing on one computer, Had win8.1 it went back to win8 with Norton antivirus.
I am lost now.
thanks for all of these ideas to try/
Same problem here too.
Windows 8.1 Pro 64bit
Issue started the same way with 2 Windows Defender updates offered at the same time.
They seemed to install, but now checking for updates give the same 2 sets of updates repeated one after the other over and over again.
I did a full Disk Cleanup with System Files cleaned as well.
Ran all the Microsoft Troubleshooters with full aggressive Windows Update cleanups.
Nothing has worked so far.
These same 2 updates are the repeating ones:
Definition Update for Windows Defender - KB2267602 (Definition 1.193.3395.0)
Definition Update for Windows Defender - KB2267602 (Definition 1.193.3002.0)
Can someone at Microsoft help fix this?
I have this on 2 different Windows 8.1 Pro 64bit computers now (my home PC and my work PC).
For the record ... I appreciate all the help these forums can deliver, but PA Bear ... really ???
When the computer was purchased .... alternate browsers .... norton's installed, flash installed ... what AV (not defender) have you and expiry date on subscription ??????????
I do realise that sometimes what we have running can upset things, and everyone has a different tweak here and there ... Windozers is not the only poster here with the problem ....
In this household there are 3 systems running 8.1, 64bit, all with varying software installed, in fact one that has only the OS, Office 2010, Defender, connection software installed ... that's it - and all three systems are having the looping definition updates occurring. We have run the suggested "fix" on all three machines - and guess what ??? - it doesn't work.
Thank you JD-1991 - an announcement from someone, anyone to let us know that they know there is a problem and they are working on it would be appreciated.
