CVMs use KMS to authorize Windows servers.

• This document is only applicable to Windows Server public images provided by Tencent Cloud. Custom and imported images cannot use the activation methods described in this document.
• Windows Server 2008 and Windows Server 2012 need to be authorized using this method. The default KMS address (kms.tencentyun.com:1668) configured for the public images of Windows Server 2016 and Windows Server 2019 is correct and does not need to be modified.

Notes

1. SPP Notification Service in Windows is used to run activation services. Make sure it runs properly, as shown in the following figure:
   
2. Some optimization software may disable modifying the execute permissions of service-related programs. For example, if the execute permissions of sppsvc.exe processes are modified, services may have an exception.
   
   Before you activate a Windows CVM, make sure that services and other features on the Windows CVM are normal.
