Consequently, the license needs to be refreshed each 180 days (6 months).
In order to avoid any inconvenience which could be caused with license activation issue, we invite you to watch for the renewal date and perform the following steps to renew your license.
1) Click on the start up menu
2) Open a Command Prompt.
SLMGR.vbs /rearm
3) You'll be invited to restart your VPS. In order to reset your license history and benefit from a new one, you would need to restart right away.
4) Log back in your VPS and open another command prompt and type the following commande lines :
cscript c:\windows\system32\slmgr.vbs /skms kms.hoststage.net
cscript c:\windows\system32\slmgr.vbs /ato
4) Log back in your VPS and open another command prompt and type the following commande lines :
cscript c:\windows\system32\slmgr.vbs /skms kms.hoststage.net
cscript c:\windows\system32\slmgr.vbs /ato
That's, your license is now refreshed and you'll be able to reproduce these steps undefinitly.
