What Is Error Code 0x803f7001?

If you see error code 0x803f7001, it means that your copy of Windows 10 isn't registering in Microsoft's database. The error occurs when Windows doesn't have a valid registration key on file for the device. There are several other reasons this Windows 10 error code could appear:

• The system didn't have enough time to communicate with the Microsoft database.
• You haven't registered a Windows 10 license key at all.
• You're operating a counterfeit version of Windows 10.
• SLUI ran into an error during activation (if the Windows 10 license key was activated through SLUI).
• You upgraded the system hardware significantly enough to confuse Windows into believing that you're on an entirely new, unregistered machine.
• You attempted to install Windows 10 on a second machine, and now this machine is no longer recognized as active in the Microsoft database.
• A virus or other malware attacked the Windows Registry.
• There's an error in the Windows Registry.
• The operating system version is out of date.
• The system drivers are out of date or not properly installed.

If you have a counterfeit copy of Windows 10, this error continues appearing until you purchase and activate a legitimate copy of Windows 10.

How to Fix the Windows 10 Activation Key Won't Work Error Code

Try these fixes in order until you can successfully use Windows 10:

1. Check the internet connection. You need a solid internet signal to register the operating system. Make sure you give the machine enough time to communicate with the Microsoft database.
2. Re-register your Windows 10 license key. If you bought a new computer with Windows 10 installed, the key will either be in a documentation file or physically located somewhere on the computer case. On a laptop, it may be located somewhere on the device's underside. If you purchased a separate copy of Windows 10, the license code will either be on the back of the physical packaging or inside an email if you purchased Windows 10 digitally. If you upgraded from Windows 8 or Windows 7, the Windows 10 registration key is the same one that you used for either of those operating systems. If that doesn't work, downgrade back to the previous version of Windows, activate your key again from there, and attempt to upgrade to Windows 10 again afterward. You can only have one device registered to one Windows 10 product key at a given time.
3. Scan the PC for malware. Use Windows Defender or another free antivirus program to run a complete security scan.
4. Run Windows Update. If possible, check for Windows updates to download any recent patches from Microsoft that could fix the problem.
5. Update the drivers. Out-of-date device drivers can cause all manner of errors, including error code 0x803f7001.

Clean the Windows Registry. Use a free registry cleaner to remove old and corrupted entries from the registry that could cause errors.

When I point my new win10 vm to vlmcsd running in a container on my server, I'm getting an odd error.

C:\Windows\system32>ver Microsoft Windows [Version 10.0.19043.1052] When I set slmgr/skms to point to my server, i get a positive message saying that it was pointed properly. When i run slmgr /ato, it sends a pop window that says "error 0x803f7001 on a computer running Microsoft Windows non-core edition, run slui.exe 0x803f7001 to display the error text."

When I run slui.exe 0x803f7001, it doesn't appear to do anything. No error, no output, no feedback... just line feed and back to the prompt.

I downloaded the ISO directly from microsoft using the media creation tool. when i run slmgr /xpr, it says "windows professional edition: windows is in notification mode."

Has something changed? Did I miss a step? Is there a way to double check which version of windows I installed? I always install pro, but maybe I clicked the wrong one this time... but I don't know how to tell. The error seems like something I would get while trying to activate the wrong version...

The text was updated successfully, but these errors were encountered:

So usually what happens is that I start to create an issue and then fill in all of the questions I currently have... and then I'm able to ascertain what I don't know and look into those bits. This time, I submitted it a bit early. I believe I was forgetting to add the /ipk VLK to the mix. I have done that now and am getting different errors.

So, everything is the same, except when I run the /ato command now, i get the message "error 0xc004f074, kms could not be contacted... no KMS server present" more words in it, but that's the gist.

Now on the windows activation applet, i see this: "we can't activate windows because we can't connect to your organization's server..." The product ID does say windows 10 pro. The volume license I used from MSFT website is there and you can read the last 'octect' of data and it is correct. product ID ends in AA4360 (I don't know if this is useful or not, so only giving the last bit in case it is sensitive info.)

Sorry to confuse things with 2 really close posts, but this was crucial in the report.

Thank you for the response, but I'm being a huge dumbass today. I forgot to open the port on my firewall for 1688. I ran a wireshark and it was immediately apparent what was happening. Sorry to bug you, but thanks for the info. I'm activated.

@lotekjunky brilliant, dont forget to close issue then 👍

@si458 right on, thank you. If you log in with Brave Browser, I've sent you a BAT tip you can collect... it's not much but it's something.
