Assessment Title

Rule Text

Spell checking provided by Microsoft Editor must be disabled.

Description

Discussion Text

The Microsoft Editor service provides enhanced spell and grammar checking for editable text fields on web pages. If this policy is enabled or incorrectly configured, Microsoft Editor spell check can be used for eligible text fields. If you disable this policy, spell check can only be provided by local engines that use platform or Hunspell services. The results from these engines might be less informative than the results Microsoft Editor can provide.

HKLM\SOFTWARE\Policies\Microsoft\Edge

If the value for MicrosoftEditorProofingEnabled is not set to "REG_DWORD = 0", this is a finding.
