Fix Microsoft Teams High CPU and Memory Usage

Microsoft Teams is an application that supports learning and working online. Due to providing high level of picture and sound quality, this application makes it difficult for low-end computers to respond.

In this article, Windowsbasics will guide you to understand why Microsoft Teams consumes a lot of RAM and CPU and how to solve this problem on Windows 10.

Why is Microsoft Teams consuming so much RAM and CPU?

Here are a few reasons why Microsoft Teams consumes a lot of RAM and CPU on Windows 10 computers:

  • Microsoft Teams is built on the Electron platform. As a result, it regularly loads a large number of libraries. Many people believe this is the reason why Teams needs a lot of RAM.
  • Microsoft Teams uses the Chromium memory management model as part of the Electron platform. It is used by Teams to build user interfaces and texts. Since it is a video calling application with a high level of picture quality, a lot of image rendering tasks need to be handled so Teams requires a lot of CPU power and RAM.
  • In addition, Teams has to run many interactive processes that are compatible with other software, so they have to use a lot of CPU power. The integration feature Microsoft Teams Meeting for Office on Windows 10 is a prime example.
