Cannot move past the "prove you're a human test"

Stop all sign-up attempts for about 24 hours, because continued retries can reset or prolong the temporary verification block.

Microsoft’s verification-block guidance says that waiting a day can sometimes remove a block; if nothing changes after 24 hours, it recommends waiting longer—potentially up to one week—without repeated attempts.^1^ This guidance is for Microsoft verification blocks generally, rather than specifically the press-and-hold CAPTCHA, but it applies to the subsequent blocking you are now encountering.

Make one controlled attempt

After the uninterrupted waiting period:

1. Open a regular browser window, not Incognito/InPrivate.
2. Temporarily disable:
   • VPN or proxy software.
   • Browser ad blockers, privacy extensions, and tracker blockers.
   • DNS/router-level filtering, if enabled.
3. Ensure cookies and JavaScript are allowed for Microsoft sites.
4. Attempt account creation once. Do not repeatedly submit the CAPTCHA if it loops again.

Microsoft documents that private browsing, content blockers, VPNs, disabled cookies, and disabled JavaScript can interfere with its security checks.^2^ Since you have already changed browsers, devices, networks, and cleared browser data, there is no value in repeating those changes independently.

If the computer runs Windows 11

Try the alternative account-creation entry point:

1. Open Settings → Accounts → Other users.
2. Select Add account.
3. Select I don’t have this person’s sign-in information.
4. Attempt to create the Microsoft account from that dialog.^3^

Stop if this route presents the same loop; repeated attempts may trigger another waiting period.

If it still fails

Use Microsoft’s official support flow:

1. Open Contact Microsoft Support from the security-check troubleshooting page.
2. Enter Microsoft account creation CAPTCHA repeatedly loops and then blocks sign-up.
3. Select Get Help, followed by Contact Support if offered.
4. Include:
   • The approximate date and time of the last failed attempt.
   • The exact displayed error or a screenshot without personal information.
   • That multiple browsers, devices, and networks were already tested.
   • That you stopped retrying for at least 24 hours and then made one clean attempt.

Microsoft directs users whose security check still will not validate to this support route.^2^
