Fix: Windows 11 Pro clave no funciona después de reiniciar

Have you recently reset your PC and suddenly your Windows 11 Pro key isn’t working anymore? You’re not alone—and there’s a fix. At KeyStoreHub, we help hundreds of users daily who face this exact issue.

Whether you bought your key from us or elsewhere, this guide will help you solve Windows 11 Pro activation problems after a reset—clearly, quickly, and without needing tech support.

Why Your Windows 11 Pro Key May Not Work After a Reset

After a Windows reset or reinstallation, it’s common for activation errors to appear. Even valid product keys can sometimes be rejected. Here’s why it might happen:

• ❌ You reinstalled the wrong edition (e.g., Home instead of Pro)
• 🔌 Your PC isn’t connected to the internet
• 🔄 Hardware changes (like a new motherboard) confuse Microsoft’s activation servers
• 🔓 Your key was never linked to your Microsoft account
• 🧯 You used a non-genuine or expired key

Don’t panic—let’s go step by step to fix it.

Fixing a Windows 11 Pro Key That Doesn’t Work After Reset

1. Double-Check Your Internet Connection

Activation needs a live connection to Microsoft’s servers. Make sure you’re online before trying anything else.

2. Verify You Installed Windows 11 Pro

Your Pro key will only work with the Pro version of Windows 11. Check your version:

• Go to Settings > System > About
• Under “Windows Specifications,” ensure it says Windows 11 Pro

If it says “Home,” you need to upgrade. Do this by going to:

Settings > System > Activation > Upgrade your edition of Windows
Then enter your Pro key from KeyStoreHub.

3. Use the Activation Troubleshooter

Microsoft provides a built-in tool that can resolve common activation problems:

• Go to Settings > System > Activation
• Click Troubleshoot

If your key was previously activated on this PC, it may reapply automatically.

4. Sign Into Your Microsoft Account

If your license was linked to a Microsoft account, signing back in can re-activate it.

• Go to Settings > Accounts > Your Info
• Log in with the same Microsoft account used before

Then return to Activation settings and click Activate.

5. Manually Re-Enter the Product Key

Sometimes you just need to reapply your key:

• Open Command Prompt as Administrator
• Type the following:

slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
slmgr /ato

Replace the Xs with your 25-digit product key from KeyStoreHub.com.

6. Contact Microsoft Support (If Needed)

If none of the above work, reach out to Microsoft Support. They can often reactivate it if you explain the reset and provide your valid key.

Avoid This Problem in the Future: Link Your Key

The best way to prevent activation issues is to link your license to your Microsoft account, Here’s how:

1. Go to Settings > Accounts > Your Info
2. Sign in with your Microsoft account
3. Go to Activation, and make sure it says “Windows is activated with a digital license linked to your Microsoft account”

This allows you to reactivate Windows automatically even after a full reset or hardware change.

Be Careful Where You Buy Your Key

If you’re seeing messages like “This key has already been used” or “Invalid license,” there’s a chance your key wasn’t genuine.
