Office apps using high memory utilization due WebView2 on W11 devices

Question

We have notice office apps (Teams, Outlook) using high memory utilization due to WebView2 in W11 devices. It is some time impacting the device performance.

is there a way to mitigate or reduce the memory utilization due to WebView2.

Answer 1

Hi Ritesh,

You can try the following methods to alleviate or reduce memory utilization caused by WebView2:

Update to the latest version: Ensure that the WebView2 controls and Office applications you are using are the latest version. New versions usually fix performance issues and memory leaks in previous versions.

Clear cache: WebView2 uses cache to accelerate page loading, but excessive cache may consume a lot of memory. Attempting to clear the cache of WebView2 can reduce memory utilization to some extent.

Disable unnecessary features: Some Office applications may use WebView2 to present specific features or content. You can try disabling these features to reduce the use of WebView2, such as disabling certain Outlook plugins or features.

Restrict simultaneous opening of tabs or windows: WebView2 may consume more memory when loading multiple tabs or windows. Try limiting the number of tabs or windows that can be opened simultaneously to reduce memory usage.

Optimize resource usage: If possible, try optimizing the resources used by WebView2, such as using lighter pages or applications, reducing embedded scripts or large media content, etc.

Monitor memory usage: Use Windows Task Manager or other system monitoring tools to monitor the memory usage of Office applications, determine when memory utilization increases, and attempt to identify specific actions or scenarios that cause an increase in memory usage.

By using the above methods, you can try to alleviate or reduce the memory utilization caused by WebView2, thereby improving the performance of Office applications.

Please let me know if you have any other questions.
