Link leads to MSE 4.9 as of April 15, 2016. The previous version can be downloaded from. If I decide to install 4.9, I will post here about any changes in the GUI. I have checked Seven Forums, but so far there are no reports similar to yours. Since you have experienced difficulty with the update, I have decided to delay installing it for now. As far as I know, no independent lab has conducted tests featuring Windows Defender 4.9 yet. Interestingly, the Engine Version (0.0) and Network Inspection Engine Version (4.0) are exactly the same as MSE 4.8, which seems to suggest that 4.9 is not a major advance. I have found that Windows Defender for 8 and 10 - which by all accounts is almost identical to MSE - received an update 6.0 at least 3 months ago. Heres the version of MS Teams installed on our workstation: Microsoft Teams Version 1. On web-based MS teams, it is working fine but on the MS Teams desktop client, it is not working. We cant click the image and enlarge it from our Chatbot. On the other hand, the previous version 4.8.204.0 (KB3063917, May 2015) was recognized as a tremendous improvement (see ). We are using this for our company, and it is very essential to us.

On the one hand, it is generally a good idea to keep security software up to date. As you have found, Microsoft does not post documentation for MSE updates. Your post last night was the first I heard of this program update for MSE.
