Top Recommended Replacements
Reboot Restore Rx (Free Edition)
FREETop Professional Free Alternative
Why we like it
100% free for basic use; restores the system to a baseline on every restart; extremely lightweight; zero configuration needed for 'kiosk' style protection.
Keep in mind
The free version lacks the 'Exclude' feature (cannot save specific folders/files) found in Shadow Defender.
Toolwiz Time Freeze
FREEBest for Simple PC Protection
Why we like it
Completely free; very simple toggle switch; allows for file/folder exclusion; works on older hardware where more complex drivers might fail.
Keep in mind
Development is slow/stagnant; interface feels dated; less robust than Shadow Defender for modern Windows 11 kernel changes.
Faronics Deep Freeze
Best for Enterprise & Schools
Why we like it
The global standard for IT admins; cloud-based management console; scheduled 'Maintenance Windows' for updates; superior security for massive fleets of PCs.
Keep in mind
Subscription-only pricing; overkill for individual power users; high cost per seat.
Sandboxie Plus
FREEBest for Per-App Isolation
Why we like it
Open-source; allows you to isolate single apps rather than the whole system; superior for 'privacy mode' web browsing; doesn't require a reboot to clear changes.
Keep in mind
Requires more technical setup; doesn't protect the entire OS configuration like a true 'system freeze' tool.
