Allow Microsoft Edge to pre-launch at Windows startup, when the system is idle, and each time Microsoft Edge is closed

This policy setting lets you decide whether Microsoft Edge can pre-launch during Windows sign in, when the system is idle, and each time Microsoft Edge is closed. By default this setting is to allow pre-launch.

If you allow pre-launch, disable, or don't configure this policy setting, Microsoft Edge pre-launches during Windows sign in, when the system is idle, and each time Microsoft Edge is closed; minimizing the amount of time required to start up Microsoft Edge.

If you prevent pre-launch, Microsoft Edge won't pre-launch during Windows sign in, when the system is idle, or each time Microsoft Edge is closed.

Supported on: Microsoft Edge on Windows 10, Version 1809 or later
