Microsoft Teams high Memory and CPU usage [Fix]

Microsoft Teams’ videoconferencing quality may sometimes come at the price of poor computer performance. It may sometimes be responsible for using high memory and CPU usage. In this guide, we will understand why Microsoft Teams can become a performance-hogging platform and also help you solve this problem on Windows 10.

Why does Teams use so much Memory and CPU power?

Here are some reasons for Teams to use so much memory and CPU power.

Microsoft Teams is built on an Electron platform, which means it constantly loads a large number of libraries. Some users believe this is why Teams demands so much memory.
Microsoft Teams uses the Chromium memory management model, which is part of Electron. Teams uses it for rendering the UI and text. Being an intensely graphical application, a lot of rendering is done, hence the high memory usage.
Also, Teams sometimes encounters compatibility issues with other programs, triggering high CPU usage. On Windows 10, the Microsoft Teams Meeting Add-in for Office is responsible for this.
