Set limit on megabytes of memory a single Microsoft Edge instance can use
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 80, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
Configures the amount of memory that a single Microsoft Edge instance can use before tabs start getting discarded to save memory. The memory used by the tab will be freed and the tab will have to be reloaded when switched to. If you enable this policy, the browser starts to discard tabs to save memory once the limitation is exceeded. However, there's no guarantee that the browser is always running under the limit. Any value under 1024 is rounded up to 1024. If you don't set this policy, the browser only attempts to save memory when it has detected that the amount of physical memory on its machine is low.

Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
