Issue: How to Fix Activation Error 0x803F7001 on Windows 10?

After changing the motherboard, I received Activation Error 0x803F7001. As far as I understand it means that Windows 10 are not activated. How to fix this error?

Solved Answer


Activation Error 0x803F7001 is one of Windows 10 errors that might bother computer users. One of the reasons why this error occurs is that Microsoft changed system activation method on Windows 10. Previous Windows versions are activated by simply entering the product key; however, Windows 10 activation operates differently. The latest Windows version uses digital entitlement and entering product key is unnecessary. This error message might also appear after a clean install Windows, changing the motherboard or Basic Input/Output System (BIOS) or The Unified Extensible Firmware Interface (UEFI) updates. The most annoying thing about this error is that it prevents from activating Windows 10. Hence, it’s important to fix Activation Error 0x803F7001.

Dealing with error 0x803F7001 in order to activate Windows and use all the features properly. Below you will find three methods that are supposed to fix this error.

Method 1. Waiting
This may sound like a ridiculous tip; however, sometimes Windows Authentication Servers just need a couple of days to catch up. When force activation does not work, all you can do is to wait for a few days. Also, you can try to reboot your computer once in a while and wait patiently.

Method 2. Manual activation with product key

If you receive Activation Error 0x803F7001 after upgrading older Windows version to Windows ten, you should try to enter previous version’s key and force Windows 10 to activate:

  1. Go to Settings, then Update & Security, and in Activation select Change Product Key.
  2. Enter the key of previously used Windows version (e.g., Windows 7, Windows 8). However, if you do not have it, enter your current Windows 10 key.
  3. After saving the changes, reboot your computer.

However, some of the users claim that they receive an error when navigating to the Activation settings. The error claims that “Activation failed because this device doesn’t have a valid digital entitlement or product key. Error code: 0x803F7001.” In order to solve this problem, you have to change the product key by following these steps:

  1. Go to Settings -> Update and Security -> Activation -> Change product key.
  2. From the list below choose your Windows 10 version and copy-paste the provided product key, and click enter:

    Windows 10 Home: YTMG3-N6DKC-DKB77-7M9GH-8HVX7
    Windows 10 Pro: VK7JG-NPHTM-C97JM-9MPGT-3V66T
    Windows 10 Home N: 4CPRK-NM3K3-X6XXQ-RXX86-WXCHW
    Windows 10 Home Single Language: BT79Q-G7N6G-PGBYW-4YWX6-6F4BT
    Windows 10 Home Country Specific: 7B6NC-V3438-TRQG7-8TCCX-H6DDY
    Windows 10 Professional N: 2B87N-8KFHP-DKV6R-Y2C8J-PKCKT

  3.  Once you receive “We couldn’t activate Windows” message, repeat the entire process, but instead of typing one of the product keys above, enter the serial number of our previously used Windows 7 or Windows 8.1.

Method 3. Phone activation

If the previous method did not work, try calling a toll free number. Though, this method won’t work if you have bought a computer with Windows 10 installed. Otherwise, you need to have your previous Windows version’s key.

  1. Open Run Command by holding Windows key and pressing R, then type “Slui 4”. Or you can simply type it in the Search Windows (Cortana) box. Click Enter.
  2. Select your Country/Region and click Next.
  3. You will receive a phone number. Dial it to get the Confirmation ID (the call is free of charge).

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
