After the upgrade from Windows 7 or Windows 8, your copy of Windows 10 should be activated and genuine. But, some users report that they received an activation error 0xc004f034, which is one of the common Windows activation errors.

We prepared a list of possible solutions for this problem and hope at least one will help you activate Windows 10.

Why does error 0xc004f03 occur on Windows?


Error 0xc004f034 is not some critical error that tells you that you won’t be able to install and activate Windows 10.

It’s just Microsoft’s message saying that Microsoft’s servers are not accessible at the moment.

It was especially the case in the first couple of days of system availability because servers were overloaded due to huge downloads, but it could eventually happen even now.

But you don’t have to worry about it because the problem will solve itself, you have to wait until the servers are available again, and you won’t have any problems activating your operating system.

On the other hand, if you don’t want to wait, you can do a couple of things to force the activation of Windows 10 right now.

How can I fix error 0xc004f034?

1. Create .BAT activation file

  1. Log into Windows 10 with your Microsoft Account, which has administrative rights.
  2. Right-click on desktop, create a text file and name it ActivateWindows10.txt.
    text 0xc004f034
  3. Open the file and post the following into Notepad:
    • @echo off
      cscript /nologo slmgr.vbs /ato
      if errorlevel 0 goto end
      goto loop
      echo Activation was successful. Press any key to close this window.
  4. Save the file in .BAT format as Windows10Activation.BAT.
    windowsbat 0xc004f034
  5. Now click on the file to run the script.
  6. Check if your Windows 10 is now activated.

So the first solution that could solve the error 0xc004f034 kms is creating a .BAT activation file in Notepad and executing it to get your Windows 10 activated.

2. Click Activate button multiple times

  1. Press the Windows key + I and choose Update & Security.
  2. Select the Activation option in the left pane.
  3. Now, click the Activate button multiple times.

5. Use the Run SLUI 4 command
