Well, I hope somebody had more luck with Wondershare Time Freeze than I did.
On XP Home I still had GUI anomalies which prevented me from activating the system protection.
Upon installation I was notified there was a possible conflict with Acronis True Image (actually Seagate DiscWizard is installed)--specifically with the driver snapman.sys. Since I have no intention of uninstalling Acronis/Seagate, that was the end of my Wondershare experiment.
No Time Freeze for me.
