I love Microsoft Security Essentials, but I'm annoyed by having to do the virus signature updates manually with each Windows Update. This could be because I have Windows Update set to download but let me choose which ones to install. However, you can use the Task Scheduler to automatically run the signature update every day.
AddictiveTips provides instructions, but on my 64-bit Win7 machine the file location was different.
Instead of
C:\Program Files\Microsoft Security Essentials\MpCmdRun.exe SignatureUpdate
I used
"C:\Program Files\Microsoft Security Client\Antimalware\MpCmdRun.exe" SignatureUpdate
So far, so good!
