Accounts: Block Microsoft accounts
Verified with Windows Security Options 25H2 — updated on July 13, 2026
Security policy
This is a Security Options policy (Windows Settings > Security Settings), applied by the security engine — not an Administrative Template (ADMX). In GPMC/gpedit it is configured under Local Policies > Security Options.
Path in the GPO console
Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Accounts Description
This setting controls whether users can add Microsoft accounts or use them to sign in. The policy is disabled by default. Blocking account addition or sign-in can reduce consumer identity use, but may disrupt applications and services that depend on a Microsoft account.
Registry
HKLM
Software\Microsoft\Windows\CurrentVersion\Policies\System Value name: NoConnectedUser
Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Security policy setting: a domain GPO (Security Settings) can overwrite this registry value at the next policy refresh. Prefer configuring it via GPMC > Security Options.
