Shadow Defender redirects all writes on a protected volume into a virtual overlay, so installed software, downloaded files and malware disappear when the machine restarts. Selected files and folders can be excluded from the overlay and kept permanently.
The small pre-activated build adds password protection, per-volume shadow mode, a command-line interface and an exclusion list for folders that must survive a restart. It runs as a background service on all current Windows editions.
