A PC image is stored on a DVD, and the end-user runs a simple application that replicates the predetermined desktop environment on their PC.
The disc locks down the PC, and ensures that the machine has the appropriate levels of patching and security.
The company said Ace creates an "assured computing environment" - an isolated standard PC configuration that can run on any PC in the extended enterprise. It delivers improved security, manageability and cost-effectiveness, according VMWare.
A spokesman for the company said, "Ace can also use digital rights management to time-out after six months, if a contractor has a six-month contract."
The system differs from network computing in that desktops or notebooks can be configured even if they are not connected to a network. The desktop runs in a sandbox environment, and is tamper-proof, said the spokesman.
