Follow these troubleshooting steps to resolve the issue:

1. Check Your Internet Connection

Ensure your PC is connected to the internet. If you’re on a restricted network (e.g., corporate or school), KMS activation may be blocked. Try using a different network.

2. Disable Firewall & Antivirus Temporarily

Security software can interfere with KMS activation. Temporarily disable:

• Windows Defender

• Third-party antivirus programs (Avast, McAfee, Norton, etc.)

• Firewall (Windows Firewall or third-party)

After disabling them, run KMSAuto Net again.

3. Manually Configure KMS Server

If automatic activation fails, try setting the KMS server manually:

1. Open Command Prompt as Administrator.

2. Enter the following commands one by one:

   cmd

    

   Download

   slmgr /skms kms8.msguides.comslmgr /ato

   (Replace kms8.msguides.com with a working KMS server if needed.)

3. Restart your PC and try activating again.

4. Use an Alternative KMS Server

If the default server fails, try another KMS server:

slmgr /skms s8.uk.toslmgr /ato

5. Check Windows License Status

Verify if your Windows edition supports KMS activation:

1. Open Command Prompt (Admin).

2. Run:

   cmd

    

   Download

   slmgr /dlv

   • Check if the license is Volume License (KMS works only with Volume licenses).

   • If it shows Retail, you’ll need a different activation method.

6. Reinstall KMSAuto Net

If the tool is corrupted:

1. Uninstall the current version.

2. Download the latest version from a trusted source.

3. Run it as Administrator and retry activation.

7. Reset Windows Licensing Status

Sometimes, resetting the licensing components helps:

1. Open CMD as Admin.

2. Run these commands:

   cmd

    

   Download

   net stop sppsvccd %windir%\ServiceProfiles\LocalService\AppData\Local\Microsoft\WSLicenseren tokens.dat tokens.baknet start sppsvcslmgr /ipk [Your_KMS_Activation_Key]slmgr /ato

   (Replace [Your_KMS_Activation_Key] with a valid KMS client key for your Windows version.)

8. Use a Different Activation Method

If KMS activation keeps failing, consider:

• Using Microsoft Toolkit (another KMS activator).

• Purchasing a genuine Windows license.

Preventing Error 0xC004F074 in the Future

To avoid this error:
✔ Always run KMSAuto Net as Administrator.
✔ Keep your KMS tool updated.
✔ Use a stable internet connection during activation.
✔ Temporarily disable security software before activation.

Final Thoughts

Error 0xC004F074 in KMSAuto Net is usually fixable by ensuring proper internet access, disabling security software, or manually configuring the KMS server. If the issue persists, try alternative KMS servers or activation tools.

By following these steps, you should be able to activate Windows successfully. If you continue facing issues, ensure your Windows version supports KMS activation or consider a legitimate license.
