Disable Microsoft Login from windows and all apps

Question

Hello,

I am using windows machines for cyber cafe, this machine is used by multiple users.

I don't want any user to login with their personal/work or school microsoft account in windows or any of the apps like edge or office.

I have already made some changes in registry to block microsoft login as below:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

Set NoConnectedUser as 3

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftAccount

Set DisableUserAuth as 1

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\default\Settings*AllowSignInOptions*

Set value as 0

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\default\Settings*AllowYourAccount*

Set value as 0

Still when I open edge for the first time it will allow microsoft account to login, same it allows microsoft login from excel, word etc.

Is there a way I can completely block microsoft account login?

I need to do this programatically using c#

Please suggest or provide me with some solution, I have already invested much of my time to resolve this.

Thanks

Hi @Dharmesh Patt , to completely block Microsoft account login, you can use Azure Policy guest configuration baseline for Windows. This policy setting prevents users from adding new Microsoft accounts on the computer. The recommended state for this setting is: Users can't add or log on with Microsoft accounts: https://learn.microsoft.com/en-us/azure/governance/policy/samples/guest-configuration-baseline-windows

You can also use Group Policies to enforce these settings across all machines. This can be done by creating a Group Policy Object (GPO) that includes the necessary registry changes and applying it to all machines.

I would also look into Local Security Policies to enforce these settings on individual machines.

You can use these samples as a starting point for the code, if you choose to take that route: https://github.com/microsoft/Windows-universal-samples

Please let me know if you have any questions and I can help you further.
