Identity Manager: Prevent users from using Identities
Verified with Windows 11 25H2 — updated on July 23, 2026
Supported on: Only Internet Explorer 5.0 and Internet Explorer 6.0
Path in the GPO console
User Configuration\Administrative Templates\Windows Components\Internet Explorer Description
Prevents users from configuring unique identities by using Identity Manager. Identity Manager enables users to create multiple accounts, such as e-mail accounts, on the same computer. Each user has a unique identity, with a different password and different program preferences. If you enable this policy, users will not be able to create new identities, manage existing identities, or switch identities. The Switch Identity option will be removed from the File menu in Address Book. If you disable this policy or do not configure it, users can set up and change identities.
