Downgrading any Version of Minecraft without a backup in Windows 7
Here's a short walkthrough on how to downgrade Minecraft without a backup in Windows 7. I am not sure if this feature is in previous versions of Windows though. Also, this may not work if you have this function disabled in Windows 7/ Your low on storage. I thought this could be helpful for people needing to downgrade back to 1.2.5 to play on the server, until it's upgraded of course. And sorry if I explain these in an incorrect way. I is a noob.

Step 4: Click the date when you updated Minecraft, since that is the previous version. *The ones
