Here is a list of Best Free Sandbox Software. These Sandbox software lets you protect your Windows system from being infected by Malware or other similar attacks. With the help of sandbox security mechanism, you can test unsafe applications, browse unsafe web securely as the applications runs in a restricted environment. Some of them are small in size and load with Windows, some do not require updates and run in background, maintain privacy, protect from key loggers, rootkits, backdoors etc.
My favorite Sandbox Software are:
As per my testing, TimeFreeze and Sandboxie are best, as these have different features. TimeFreeze is simple and only require restart to clean the system, while Sandboxie lets you run any program in sandbox mode by simple right clicking.
TimeFreeze is a simple and small sandbox utility which lets you protect your Windows system from infection by suspicious files and applications. First install TimeFreeze and restart the PC, otherwise it will not start its services. Now you can make it active from system tray icon. When the program is in ON state, every single task, like download of a file, rename or moving a file or folder will be reverted back automatically to its previous state, after reboot. In other words "Every change in system partition will be discarded after reboot". To achieve this, just restart the Computer. You can add programs/files/folders to the exception list if required, and the changes made by/to this list will not get affected when reverting. The program is very small in size (just 2.75 MB in size). It sits in the system tray and you can start and stop it as per need.
Sandboxie is based upon sandbox based security mechanism used to run an application in an isolated environment. It restricts programs or attackers to run arbitrary or malicious code on your PC by creating a sandbox environment. The program has its own desktop and start menu. You can run any installed program through it, or install a new one from its "Run any program sandboxed" command from Windows Start menu. It shows a thick yellow outline around any program which is run through it. The programs installed using it will not be able to modify the system and registry. You can run any web browser through it and it creates a safe virtual wall between your web browser and PC. You can safely explore files and folders by using it on your Computer. The program is small in size and is easy to install. The program installed through it will not be visible in Windows Start menu. This program can be used for testing of untrusted programs and surfing the unsafe web. For more security, you can even Sandbox Tor Browser.
BitBox provides virtual environment for secured web browsing. It is based upon "Browser in the Box" concept. It has Firefox and Chrome as standalone web browsers.

It stores all the configuration data of the web browser in its folder for each user. Overall the size of the program is big but it maintains your privacy and keeps you safe from Malware or similar attacks.
