is there a limit to the number of devices you can register in your windows admin account? currently on 29

Thanks for getting back to me Martin.

1. Account Type:
   • Is the affected admin account a local account or a Microsoft account? Microsoft account
   • Is the account associated with a personal or organizational profile? Personal account
2. Windows Version: What version and edition of Windows are you using (e.g., Home, Pro, Education)? Press Win + R, type winver, and provide the exact version number shown. Home
3. Error Details: What happens when you try to sign in to the new admin account? Is the "Sign In" button grayed out or unresponsive? Do you see any error messages or codes when attempting to sign in? No errors, sign in button but is greyed out

For more context:

We are removing Admin 1 from devices and adding devices to the Admin 2 account (29 so far)

The aim is to remove an old supplier who managed our devices to be more self managed.

Dear Talkr admin,

Thank you for reaching out with your concerns about adding and signing in to an admin account on your Windows device.

I understand this can be a confusing issue, and I’m here to help clarify and provide troubleshooting steps.

Key Points to Address Your Concerns

1. No Explicit Limit for Admin Accounts: Windows does not impose a hard limit on the number of administrator accounts you can add to a device. However, certain configurations or policies (especially on organizational or domain-connected devices) may restrict access or create conflicts when managing multiple admin accounts.
2. Device Registration in Your Microsoft Account: A Microsoft account does have a limit of 10 devices for features like Microsoft Store apps or content syncing. However, this limitation does not directly affect the number of admin accounts that can log in to a device unless the devices are registered to an organizational account with specific restrictions.

To investigate the issue further, please provide the following details:

1. Account Type:
   • Is the affected admin account a local account or a Microsoft account?
   • Is the account associated with a personal or organizational profile?
2. Windows Version: What version and edition of Windows are you using (e.g., Home, Pro, Education)? Press Win + R, type winver, and provide the exact version number shown.
3. Error Details: What happens when you try to sign in to the new admin account? Is the "Sign In" button grayed out or unresponsive? Do you see any error messages or codes when attempting to sign in?

While we wait for more information, you can attempt the following steps:

1. Verify the Account's Status. Ensure that the new admin account (Admin 2) has been successfully created and assigned administrator privileges. Go to Settings > Accounts > Family & Other Users, and confirm that Admin 2 is listed as an administrator.

2. Check Device Login Settings. Confirm that the device allows multiple administrator accounts to log in. Go to Settings > Accounts > Sign-in Options and review policies related to account sign-ins. Check for any restrictions under Local Security Policy (available on Pro or Enterprise editions).

3. Check Organizational or Policy Restrictions. If the device is part of an organization or domain, Group Policies or Azure AD rules might limit the number of admin accounts or device registrations. Contact your IT administrator to verify policies.

Once you provide the requested information, I’ll guide you through additional steps or escalate the issue if necessary. In the meantime, try the troubleshooting suggestions above and let me know the results.

Looking forward to hearing from you soon.
