Question details
The user is unable to complete the Microsoft product key redemption process because the webpage freezes after completing the CAPTCHA verification.

- Product
- Microsoft Office
- Device & OS
- not provided
- Scenario
- Redeeming a Microsoft Office product key and submitting payment details online.
- Observed behavior
- The browser gets permanently stuck on the confirmation screen displaying 'Success! You've proven you're not a robot', preventing the finalization of the account setup.
Ensure you have a stable internet connection and keep your 25-character Microsoft product key written down in case you need to restart the redemption process.
Clear Browser Cache and Use Incognito Mode
Clearing corrupted cookies or using a private browsing window is the most effective way to bypass script errors during the Microsoft verification process.
Browser cache and tracking cookies can sometimes conflict with Microsoft's secure authentication scripts, causing the CAPTCHA page to freeze even after successful verification.
Launch your web browser and open an Incognito Window (Chrome) or InPrivate Window (Edge) by pressing Ctrl + Shift + N.
Go to the official Microsoft product key redemption page (setup.office.com) in the new private window.
Sign in to your Microsoft account, enter your 25-character product key, and complete the payment and robot verification steps again.

Disable Browser Extensions and Ad-Blockers
Turn off third-party extensions that might be blocking the background redirection scripts required after the robot check.
Switch to an Alternative Browser or Network
Using a completely different browser or internet connection can bypass localized network or software glitches.

Frequently Asked Questions
Did my Microsoft product key get redeemed if the page froze?
If the page froze immediately after the robot verification and before the final confirmation screen, the product key may not be attached to your account yet. You can verify this by visiting the 'Services & subscriptions' page in your Microsoft account. If your product is not listed, you will need to try redeeming the key again.
Why does the Microsoft robot verification page get stuck?
This issue is typically caused by outdated browser cache, restrictive privacy extensions blocking redirect scripts, or brief network timeouts that prevent the browser from receiving the final success signal from Microsoft's servers.
Can I bypass the payment details requirement when redeeming a key?
If you are redeeming a prepaid Microsoft 365 subscription, Microsoft usually requires a backup payment method for future recurring billing. You cannot bypass this step during redemption, but you can turn off auto-renew in your account settings immediately after the setup is complete.
