How to Fix ‘Windows Not Genuine’ After Using KMSpico

Blog Article

If you’ve used KMSpico to activate Windows but suddenly see a "Windows is not genuine" warning, your activation may have failed or been revoked. This guide will help you fix the issue and restore proper activation—whether through KMSpico or alternative methods.

Why Does "Windows Not Genuine" Appear After KMSpico?

Several reasons can cause this error:

Windows Update removed the KMS activation.

Antivirus or Defender blocked KMSpico’s background process.

KMS server emulation failed (expired ticket or connection issue).

Microsoft blacklisted the KMS server used by KMSpico.

5 Fixes for ‘Windows Not Genuine’ Error

1. Re-run KMSpico as Administrator

Sometimes, the activation just needs to be refreshed.

Disable antivirus (temporarily).

Right-click KMSpico → Run as Administrator.

Click "Activate" and wait for completion.

Restart your PC and check activation status (slmgr /xpr in Command Prompt).

2. Manually Reset KMS Activation

If KMSpico fails, try manual commands:

Open Command Prompt (Admin).

Enter these commands one by one:

slmgr /upk  

slmgr /ckms  

slmgr /rearm  

slmgr /ipk [Your-KMS-Product-Key]  

slmgr /skms kms8.msguides.com  

slmgr /ato

(Replace [Your-KMS-Product-Key] with a valid KMS client key for your Windows version.)

3. Use a Different KMS Server

If Microsoft blocked the default server, switch to a new one:

Open CMD as Admin.

Type:
cmd
```
slmgr /skms kms.digiboy.ir  

slmgr /ato
```
(Alternative KMS servers: kms.lotro.cc, kms03.zhost.xyz)

4. Remove KMSpico & Use HWID Activation (Permanent Fix)

If KMS keeps failing, switch to HWID (Digital License) Activation:

Uninstall KMSpico completely.

Download Microsoft’s Activation Scripts (MAS) from GitHub.

Run HWID Activation for a permanent, genuine license.

5. Clean Install Windows (Last Resort)

If nothing works, a fresh Windows install removes all activation issues:

Backup your data.

Create a bootable USB with Microsoft’s Media Creation Tool.

Install Windows and activate using a genuine license or HWID.

Preventing Future Activation Issues

✔ Disable automatic KMS updates (if using KMSpico long-term).
✔ Add KMSpico to antivirus exclusions to avoid false positives.
✔ Use a firewall rule to block Microsoft’s activation checks.

Is There a Legal Way to Fix This?

If you want to avoid KMSpico entirely, consider:

Buying a genuine Windows license (Best for long-term use).

Using Windows unactivated (Limited customization but functional).

Switching to Linux (Free & open-source alternative).

Final Thoughts

The "Windows not genuine" error after KMSpico usually means the activation was disrupted. By re-running KMSpico, changing KMS servers, or switching to HWID activation, you can restore full functionality.

⚠ Warning: KMSpico is not legal for commercial use. For a 100% safe solution, consider official Microsoft licenses or free alternatives like Linux.
