Error 0xC004F035 — Cannot activate using a volume licence key

Error 0xC004F035: Cannot activate using a volume license key

This error occurs in: Windows 10, Windows 11, Windows Server.

Cause

An attempt to activate a computer using a volume license key (Volume License) on a device that is not intended for such activation, or the computer does not have an OEM or MAK BIOS.

Symptoms

• During activation, the message appears: "Cannot activate using a volume license key"
• Error code: 0xC004F035
• English version: "The computer could not be activated with a Volume license product key"

Step-by-step solution

Use a MAK key instead of a KMS key. Or configure a proper KMS environment. Make sure you are using the correct type of key for your Windows version.

Solution for Windows Server

1. Open PowerShell as administrator
2. Enter the key:

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

1. Activate:

slmgr /ato

1. Check the status:

slmgr /xpr

Verification

After performing the steps, check if the activation was successful:

• Windows: Settings → System → Activation → should be "Windows is activated"
• Or: slmgr /xpr in the command line

Still not working?

If the above steps did not help:

1. Check the date and time — they must be correct (an incorrect date can block activation)
2. Temporarily disable antivirus and try again
3. Check the internet connection — online activation requires a connection to Microsoft servers
