I do a lot of software testing for this website almost on daily basis. Most of the work are done inside a virtual machine that can be reversed back quite easily. But even that, I always wish there is a nice tool that can protect and undo the changes in an effortless way. And if you are the same as mine, maybe take look this Time Freeze Tool from this Singapore-based Toolwiz Software company.
Toolwiz Time Freeze is a Free sandbox tool that keeps your system safe from any unwanted changes and malicious activity in low disk level. With a simple click, it puts your actual system under a virtual protection environment like a sandbox on the fly, in which you can evaluate software, test suspicious files, or even perform online activities.
Toolwiz provides two methods protecting your system, the TimeFreeze protection mode and the File protection mode.
The TimeFreeze protection mode protects the whole system. When started, it creates a virtual sandbox as a copy of the real system. All the work done from this point will be only saved in this virtual copy. Later on, when stopping, you can decide whether to keep the changes you’ve done during the period or drop them to reverse the system back to where it was.
The File Protection mode is to protect the files or folders. You can add any files or folders, except the system files, to the protection vault to keep them from unwanted changing/viewing by others. You can also enable password protection in this mode as well.
Toolwiz Time Freeze works on most modern Windows system, from XP up, both 32-bit and 64-bit editions.
