Microsoft Edge Blocker Toolkit is designed for disabling automatic delivery and installation of Microsoft Edge.

Microsoft will distribute Microsoft Edge (Chromium-based) through Automatic Updates for Windows 10 version 1803 and newer more frequently for security purposes. Microsoft Edge Blocker Toolkit is intended to allow those wishing to block automatic delivery of Microsoft Edge (Chromium-based) to machines in environments where Automatic Updates is enabled.

The Blocker Toolkit will not expire.

For computers running Windows 10 version 1803 and newer, Microsoft Edge Blocker Toolkit prevents the machine from receiving Microsoft Edge (Chromium-based) via Automatic Updates. It does not, however, block you from manually installing Microsoft Edge (Chromium-based).

This toolkit contains the following components:

Executable blocker script (.CMD)

Group Policy Administrative Template (.ADMX + .ADML)

Supported Operating Systems

The script creates a registry key and sets the associated value to block or unblock (depending on the command-line option used) automatic delivery of Microsoft Edge on either the local machine or a remote target machine.

Registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftEdgeUpdate
Key value name: DoNotUpdateToEdgeWithChromium

Switches used by the script are mutually exclusive, and only the first valid switch is acted on from a given command. The script can be run multiple times on the same machine.

Switch Description

/B Blocks distribution
/U Unblocks distribution
/H or /? Displays the following summary help: This tool can be used to remotely block or unblock the delivery of Microsoft Edge (Chromium-based) through automatic Updates.

Usage:

EdgeChromium_Blocker.cmd [] [/H]
B = Block Microsoft Edge (Chromium-based) deployment
U = Allow Microsoft Edge (Chromium-based) deployment
H = Help
Examples:
EdgeChromium_Blocker.cmd mymachine /B (blocks delivery on machine "mymachine")
EdgeChromium_Blocker.cmd /U (unblocks delivery on the local machine)
