Reinstalled Windows 11 pro and now it's home edition. How do I get my original pro key?

Hi @3gfry 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thank you for sharing this—it’s understandably frustrating to reinstall Windows and find yourself downgraded to Home edition, especially when you know your system originally ran Pro. You’ve already taken the right step by noticing the mismatch, and we’ll walk through how to recover your Pro license and get your system back where it belongs.

To restore your original Windows 11 Pro edition after reinstalling, you’ll need to reapply the digital license or product key that was previously linked to your device. If your system came with Pro, it should activate automatically once the correct edition is installed.

Steps to Restore Windows 11 Pro After Reinstalling Home Edition

1. Check Activation Status

• Go to Settings > System > Activation.
• If it says Windows is not activated, click Troubleshoot and follow the prompts.
• If your device previously had a digital license for Pro, Windows may detect it and upgrade automatically.

2. Reapply the Windows 11 Pro Product Key If you have a physical or digital key:

• Press Windows + I, go to System > Activation > Change product key.
• Enter your original Windows 11 Pro key and click Next.
• Windows will verify and upgrade your edition.

3. Use Generic Pro Key to Trigger Upgrade (Then Activate) If you don’t have the key but know your device had Pro:

• Use this generic key to switch editions:VK7JG-NPHTM-C97JM-9MPGT-3V66T
• Go to Settings > System > Activation > Change product key, enter the above key.
• This will upgrade your system to Pro, but it won’t activate it.
• Once upgraded, Windows may automatically activate using your device’s digital license.

4. Confirm Digital License Is Linked to Your Microsoft Account

• Go to Settings > Accounts > Your Info.
• Make sure you’re signed in with the same Microsoft account used previously.
• If your Pro license was linked to this account, activation should occur automatically.

5. Reinstall Windows 11 Pro Directly If the system keeps defaulting to Home:

• Create a bootable USB using the Windows Media Creation Tool.
• During installation, choose Windows 11 Pro manually.
• Skip entering the key during setup—Windows will activate later if the license is valid.

You’ve already taken the right steps—just a few more and your system will be back to full Pro functionality. Let me know if you’d like help creating installation media or verifying your activation status. You’re very close to resolving this smoothly.

I've tried most of what you suggested. Purchased the HP used and seller claims it was Windows 11 OEM install. I am assuming that the Windows pro install is somehow linked to previous owners HP account.

Thanks for clarifying @3gfry. 

If the HP device was originally set up with an OEM Windows 11 Pro license tied to the previous owner’s Microsoft account, then unfortunately that digital entitlement won’t transfer automatically to you. 

Here’s how to move forward based on your situation:

1. Check for Embedded OEM Key (Just in Case)

Some HP systems include a Windows key embedded in the BIOS:

• Open Command Prompt as administrator
• Run:
  wmic path softwarelicensingservice get OA3xOriginalProductKey
• If a key appears, it’s likely a Home edition key. If blank, the system may rely solely on digital licensing.

 

2. Confirm Current Activation Status

Go to Settings > System > Activation:

• If it says Windows is activated with a digital license, it’s likely for Home edition.
• If it says Not activated, you’ll need a valid Pro key to proceed.

 

3. Options to Upgrade to Windows 11 Pro

Since the previous owner's Pro license isn’t transferable, here are your options:

 

A. Purchase a New Windows 11 Pro License

• Visit Microsoft Store or use the Upgrade button in Settings > System > Activation
• This links the new Pro license to your Microsoft account

 

B. Use a Volume License or Retail Key (If Available)

• If you have access to a valid retail or volume license key (e.g., from work or school), enter it under Change product key

 

C. Stay on Home Edition

• If you don’t need Pro features (BitLocker, Remote Desktop, Group Policy), Home may suffice for everyday use

Let me know if you’d like help comparing Home vs Pro features or navigating the upgrade process. You’ve already done a great job isolating the issue, and with a valid key, you’ll be back on Pro in no time.

Thanks,

I cannot believe I paid 1600 for the omnibook ultra and after MONTHS of struggling to get the computer set up for RDP/Virtualization. I'm in school still learning, best buy was clueless. Guess what? The 1600 dollar computer had windows 11 home. Not pro. And guess what I don't have 200 more dollars to upgrad.  I WILL NEVER BUY HP AGAIN

It defaulted to Home because your BIOS has a Home key. Just switch back to Pro by entering your original key in Settings → Activation. If you’ve lost the key, you can either recover it from your Microsoft account or just buy a new Pro key I got mine from Digitlogs and it worked fine.
