What OS does Xtra PC use?

It comes with a Linux OS that is easy to install and 16 GB of storage on a USB drive. You also get a DVD that teaches you how to use that OS and some extra software. Another alternative to Xtra-PC is the Kali Linux Bootable USB, which includes 16 GB of storage.

Does Xtra PC work with Windows XP?

You can run the product off the DVD, a flash drive, or install it directly to the hard drive (erasing the old operating system). I tried it on a few different XP-era computers and didn’t need any drivers. Even wireless and Ethernet worked perfectly.
