Wiuth Shadow Defender's thread getting so popular, it seems the release of Power Shadow 2008 went unnoticed.. So, now, we have 3 main alternatives.. Returnil, Shadow Defender and PowerShadow.. Don't think their English webpage is up yet.. but from what I can translate and see, their new features include.. Translating from the whats new table at at http://www.powershadow.com/cn/pro/2008.html , we have 1. Added Support for Dual/Quad Core CPUs. 2. Added password protection for going into shadow Mode, preventing unauthorised user from changing system 3. Added support for moving My Documents, Desktop, IE, Outlook, allowing them to store files normally 4. Added suppport for Multi-OS <-- Don't understand what this really means.. 5. Added "Hide" functionally <-- Don't know what is this funcnality.. 6. Support Hibernation and User Switching 7. Support Multi Harddisk Wonder when the English version will be release..
