How do I install Minecraft 1.7.3 Snapshot 13w48b?

Open your launcher, create a new profile, name it something like 'snapshots', and check 'Enable experimental development snapshots'. Save and select that profile from the launcher dropdown to run the snapshot.

Will my worlds work in this snapshot?

Generally yes, but always back up your save files before testing snapshots. Worlds made in snapshot builds might have compatibility issues with earlier versions, so don't test on worlds you care about.

How do I go back to the normal Minecraft version?

Just select the regular version from the profile dropdown at the bottom left of the launcher. Your worlds stay the same either way.

Can I use mods with this snapshot?

Mods built for 1.7.3 might work, but snapshots can break mod compatibility. If you need mods, stick with the stable release version instead.

What's the difference between the client and server downloads?

Client is what you run to play. Server is for hosting multiplayer worlds. The Windows EXE is just the JAR in a different format for Windows users.
