From there you can select the Products tab and verify whether Windows Defender is enabled or not.If not, go ahead and put a check in the box as shown below. Once this is done your Windows Defender clients should start receiving updates from your Software Update Point.
Found a script that does fix the issue most of the time. Copy this to .vbs, run it on the client machine having issues. This is automatically be done with the Cumulative Update 3 for SCCM: S In my case there were a lot of Bad Mifs which exceeded the size limit, after i removed them, one of my Clients just started downloading some definitions....don't know if this depends from each other..maybe you got similar Problems.I figured out my own problem here and it turned out to be due to the fact that a maintenance window being applied to another collection other than the one the definition updates were being deployed to was preventing the installation of the updates.All I needed to do to fix the problem was change the option on the User Experience tab of the automatic deployment rule relating to allowing software installation outside of maintenance windows.It seems that machines can only receive one maintenance window and they can't be set for each individual collection that a deployment is targeted at as I expected.
