How to try a program on Windows without touching your PC

Downloaded a program you want to try? In Mezi Box it runs with low permissions: Windows itself stops it from writing to your folders, the Registry or other programs.

Step by step

  1. Download and install Mezi, then choose the folder where instances will live.
  2. In Mezi, click "Add app" and browse to the program’s file. Create the free account, which unlocks Mezi Box.
  3. Click "New instance" and give it a name, like "Work" or "Personal".
  4. When creating the instance, turn on Mezi Box and open the program. When you finish, delete the instance and everything it wrote goes with it.

The free plan opens 1 instance at a time, alongside your normal app. With Pro, you can open as many as you want at once.

Tip

Mezi Box is an extra layer, not an antivirus: apps in it can still read files on your PC. For very suspicious programs, prefer a virtual machine.

Frequently asked question

Does every program work in Mezi Box?

No. It is in beta, and programs that need to write outside their own folder may fail. Games with anti-cheat, like Roblox, don’t open in it.
