Tails OS is a free and privacy-focused operating system that is designed to protect you against malware, censorship, and surveillance.
Tails OS is based on Debian Linux and boots from a USB stick.
When you use Tails OS, everything you do is stored in RAM and not on disk. This means that when you shut down Tails OS, all of your data is deleted.
Tails OS also includes a number of privacy-focused software applications, such as the Tor browser.
To get started with Tails OS, you will need a USB stick with at least 8GB of memory. You can then download the Tails OS image and flash it to the USB stick using a tool like Etcher.
Once you have flashed the Tails OS image to the USB stick, you can boot from it by holding down the Shift key while clicking on the Restart button from the Start menu.
Tails OS will then load and you will be able to use it to browse the internet anonymously and securely.
