InformationThis policy setting sets the ProcessExtensionPointDisablePolicy on Microsoft Edge's browser process to block code injection from legacy third party applications.
Note: Per Microsoft, only turn off the policy if there are compatibility issues with third-party software that must run inside Microsoft Edge's browser process.
The recommended state for this setting is: Enabled.
If this policy is set to Disabled, it may have a detrimental effect on Microsoft Edge's security and stability as unknown and potentially hostile code can load inside Microsoft Edge's browser process.
Compatibility issues with third-party software can occur.
SolutionTo establish the recommended configuration via GP, set the following UI path to Enabled:
