On Cloud VPS Windows, there is preinstalled
(previously: ParallelsTools) software. It is virtualization support software necessary for proper work of VPS. However, it sometimes need to be updated.
Updating VirtuozzoTools is very simple. You just need to connect to your VPS through control panel's console or remote desktop. If after logging in you see a window like below please wait for a moment until installation finishes and click the left button to restart the server.
※If you see neither of the windows, it just means that VirtuozzoTools is up to date and do not need updating.
