I would like to know how to disable and enable Microsoft Security Essentials from the command line.

This is a common procedure on build machines in order to speed-up the build process.

To disable from the (elevated) command line:

net stop MsMpSvc

To start from the (elevated) command line:

net start MsMpSvc

However, you may get similar results by simply going in to the configuration and disable scanning on your solutions/build folder

  • I'm getting "System error 5 has occurred. Access is denied." (I ran command prompt as admin).

  • Hi @BornToCode - if you are running as an admin, and, your machine doesn't have multi admin levels/domain with further restrictions, this should work... I have a busy day, but, my contact details are in my profile - feel free to send me an email and I can take a quick look for you later to see if anything weird is going on/see if there is something I can do quick.
