Activate Windows License

Tencent CVM uses KMS for granting authorization to Windows server. Currently, only Windows 2008 and Windows 2012 need such authorization.

1. Automatic activation tool

Tencent Cloud encapsulates a script for Windows activation on QCloud that simplifies the steps for manual activation.

2. Run the activation manually.

1) Click "Start" - "Run", enter cmd.exe to open the console window.

2) Enter the following commands in turn:

cscript /nologo %windir%/system32/slmgr.vbs -skms kms.tencentyun.com:1688
cscript /nologo %windir%/system32/slmgr.vbs -ato

Note 1:
On some systems, if there is a problem with the system clock, error will occur during manual activation. In this case, you need to synchronize the system clocks. The synchronization between clocks is performed as follows: Enter the following commands in the console window:

w32tm /config /syncfromflags:manual /manualpeerlist:"ntpupdate.tencentyun.com"
w32tm / resync

Note 2:
SPP Notification Service on Windows is used to perform activation-related services and its normal operation needs to be ensured.

Some optimization software may disable the change to execute permissions of service-related executables. For example, the change to the execute permission of sppsvc.exe process can cause abnormal operation of service.

Before you attempt to activate Windows, make sure the service and other basic functions on Windows are in a normal condition.
