Last week I fixed a 17 year old laptop and installed Windows 7 on it. I then installed MSE on it. Even though Windows 7 worked OK on it I wanted better compatibility and security on the Internet. I took the plunge and did a free upgrade to Windows 10. Surprisingly the upgrade went quite well. Note before it started the upgrade it looks for compatibility problems. It is ironic that the only problem it found was that it needed to remove MSE.
I am also having this problem? any fix available?
Edit...
Managed to get it working by enabling Win Update (had it disabled) any way to keep the Win Update disabled but still update MSE?

When you check for updates using MSE itself the error message that the update has failed is misleading.
Look carefully at the sequence of screenshots in my post #9.
You will see that whatever network issue is that's causing the message, it actually occurs after the definitions have been successfully updated.
ok but will it auto update in the background? i got some event log errors witch point to a failed update
Microsoft Security Essentials 4.10.209.0 updates fine.
Ignore and close the error message when it appears.
You will see the definition files have been updated.
Hi, I've been having this problem as well. I noticed MSE automatically updates definitions. If I do another update by pressing the Update definitions button ,the error comes up at the Installing.... stage. However, the definitions still update OK when the operation finishes. I also noticed if I press the Update definitions button again, the error disappears when the search operation finishes.
I hope that helps.
I maybe fixed by reinstalling MSE, remove SoftwareDistribution folder (C:\Windows\SoftwareDistribution) and Check updates in WU again. Then MSE check new updates without this Error table.
like i said it works when WU is enabled (service) once disabled it wont work anymore like it used to...
