Troubleshooting Windows Activation: Changing Your Product Key to a Volume License KMS Key | 無法啟用 Windows，如何更改windows 序號為大量授權 KMS

 

If you've installed Windows using an ISO downloaded directly from the Microsoft website, you might find that your organization's Key Management Service (KMS) activation method doesn't work. 

This is because the default product key is not a KMS key. To resolve this, you need to change your Windows product key to a KMS version.

For example, you can refer to the Microsoft documentation for KMS client setup keys: https://learn.microsoft.com/zh-tw/windows-server/get-started/kms-client-activation-keys?tabs=server2025%2Cwindows1110ltsc%2Cversion1803%2Cwindows81

Change the product key to the Windows 11 Professional version: W269N-WFGWX-YVC9B-4J6C9-T83GX. Then, follow these steps to activate Windows:

1. Go to System > Activation and select Change product key.
   
   
   
   
   
   
2. Enter the product key: W269N-WFGWX-YVC9B-4J6C9-T83GX.
   
3. Click Activate. Alternatively, you can use your organization's provided activation method.

如果從微軟官網自行下載 Windows ISO 安裝後，會發現無法使用單位的 KMS 啟用方式。這時候就要先將 Windows 的產品金鑰改為 KMS 版本，例如參考: https://learn.microsoft.com/zh-tw/windows-server/get-started/kms-client-activation-keys?tabs=server2025%2Cwindows1110ltsc%2Cversion1803%2Cwindows81。將產品金鑰改為 Windows 11 專業版序號 W269N-WFGWX-YVC9B-4J6C9-T83GX。

接著按照以下步驟啟即可。

1. 進入系統，選擇更改產品序號

2. 填入  W269N-WFGWX-YVC9B-4J6C9-T83GX

3. 按下啟用。或是使用單位提供的啟用方式即可。
