Limit CPU Usage By Microsoft Security Essentials

Mse ThumbnailWhen it comes to using the internet efficiently, bandwidth usage is something that you should keep a track of. Similarly, when it comes to using the computer, you should watch out for CPU usage.

Though the operating systems take utmost care to relatively distribute the CPU and maintain a harmony among applications, there are certain tools that force the machine to allot them the processor on a priority basis, thus compromising on other heavier tasks.

Anti-virus tools are often the culprit in such scenarios. Usually, they eat up a huge portion of CPU, and the like; for example Microsoft Security Essentials (MSE) is set to consume 50% of the CPU by default.

So, during a security scan, if you are running some other heavy tasks that require more attention, then you can limit the CPU consumption of MSE. Here’s how.

Step 1: Launch MSE. It should be sitting in the system tray.
