Linux is a free, open-source operating system based off of Unix mainframes, given to the world in 1991, by Linus Torvalds. There are hundreds of versions.

The easiest Linux to transition from Windows is…
Linux Mint (MATE Edition) built on Ubuntu/Debian
 LinuxMint.com/download.php (.deb not .exe packages, when you want something not in the giant free library, that just takes a mouse click to install)

You can TEST Run off a DVD or USB stick.No install need! =)
DVD www.FreeIsoBurner.com
USB https://unetbootin.org
Warning: If your wifi is Broadcom, you’ll have a few hoops (use Ether 1st)

Make sure
you find the setting for Covid
(not the 40+ other projects concurrently running)
OR,
again, you can toss a donation our way
to put a LOT of rigs up
& eat a (lot) of electricity(!)

Oh, yes:
We’re surprised which of our archived rigs are SLOW as a snail in January.
But
on the plus side,
Tontos’ workload now ranks
53,936 of 253,900
