Solution 1Recommended

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.

1
Open a private browsing window

Launch your web browser and open an Incognito Window (Chrome) or InPrivate Window (Edge) by pressing Ctrl + Shift + N.

2
Navigate to the redemption page

Go to the official Microsoft product key redemption page (setup.office.com) in the new private window.

3
Sign in and re-enter details

Sign in to your Microsoft account, enter your 25-character product key, and complete the payment and robot verification steps again.

Clear Browser Cache and Use Incognito Mode
Check your account status: If you are unsure whether the key was already redeemed during the freeze, log into your Microsoft account and check the 'Services & subscriptions' tab before attempting to redeem it again.

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.
