This article applies to Windows Virtual Private Server accounts.
It is not possible to install any Windows Updates as some may not be compatible with Virtuozzo. Due to this, updates that are possible (i.e. have passed testing by SWSoft) are installed on the VPS hardware nodes during scheduled maintenance. Once this is restarted, all VPS' on the hardware node are updated with the latest Virtuozzo compatible Windows Updates.
WARNING: Do not attempt to install Windows Service Pack 2 as this will cause serious problems which can only be resolved by a complete reinstall of your VPS.
