微軟繼續修改Vista的授權協議，最新的修改允許消費者在沒有硬盤的PC上或在中央集權服務器硬件虛擬機中運行Windows Vista。但是，這次改變并未涉及所有Windows消費者，這只是用以滿足企業用戶的需求。實際上，只有微軟軟件保險客戶可以有此協議。

原文如下：

“For Software Assurance customers using Windows Vista Enterprise, we’re adding two new ways to license and deploy the operating system. They are:

1) The license right to use Windows Vista on diskless PCs

2) The availability of a subscription license called Windows Vista Enterprise Centralized Desktops (VECD) which allows customers to use Windows in virtual Machines centralized on server hardware,” revealed Scott Woodgate, Director in the Windows Business Group.'
