Final note: If you saw “Minecraft Beta 1.7.3 Download Free 2021” on a sketchy website, ignore it. Use the official method. Your computer (and Mojang’s terms of service) will thank you.

Once you have a legitimate copy installed, you can explore the many mods designed for this version. For server owners, forks like (a fork of CraftBukkit for Beta 1.7.3) provide performance enhancements and bug fixes while keeping the original gameplay intact.
