ShadowStor ShadowUser Pro insulates your PC from all manner of day-to-day problems. It runs an exact duplicate of your system as a virtual machine, known as ShadowMode. If a software installation goes wrong or a virus hits, you can completely discard the virtual machine. Conversely, if you've successfully installed software or made other important changes, you can write all or part of the virtual machine back to the actual, physical PC's storage.

With your system in ShadowMode, you can surf the Internet without a trace of unwanted cookies, histories, temporary files, spam applications, or spyware; instantly undo accidental or malicious changes to your PC; safely test new applications, updates, and patches before saving those changes; use the scheduling and user-security features for securing public-access computers; and reduce system-maintenance costs and computer downtime.
