How to go back to a newer version of minecraft?

It sounds really weird I know, but to run a certain mod it said I had to run minecraft 1.7.2 at least once. So I figured out how to do it, but now I want to go back to 1.7.4. How do I do it? Am I blind to the version list or something? Lol please answer!

Laptops for Light Gaming and Photo Editing?

I'm looking for a cheap laptop, the highest I can go is $450.
The games that I would play would be Minecraft and possibly I'll download Steam and get DayZ or The Walking Dead Season Two. More than likely I'd download three or so free games.
For photo editing, I wouldn't download a huge program for experts, just something small and simple.

Thanks for helping!

Added (1). I forgot to add that I would add mods to my MineCraft.

Is upgrading from a GT 610 1gb to a GT 640 1gb worth it?

Before you say no and get money for a better GPU, I'm only looking to play games such as minecraft or garrys mod. I'm also able to over clock it with MSI afterburner. I just want to know if there will be a difference between both cards. I know that the GT 610 is 64 bit and GT 640 is 128 bit. It is also better in general, I just want to know if its worth it.

Its frustrating me! I'm a complete mod noob! I wanna get like build craft, then eventually Galaticraft- but i can't because I can't figure out how to do it! I know i need the most recent things which is 1.7.4/2?

Please someone give a guide on how to do it! Links too would be really helpful! Like WinRAR, explain what it is/does? If you do I will worship you.

How to get more noticed on YouTube?

So I spend about 4 hours a day on editing, and trying to perfect my video, then the rest of the day is spent on recording footage with my friends. I don't mean to sound cocky, but I feel that my subscriber count is tiny compared to my video and editing quality. I work so hard on getting perfect clips, making other peoples sound work well etc. Even if all you could help me with is subscribing! (Will be starting subscriber shout-outs soon so get in there early! )
Does anyone have any tips for getting more known on YouTube?
I have tried getting people to dual-com with me, but no-one seems to want to.
I play Minecraft, Just Cause 2. Garry's mod, and more!
I also use plenty of relevant tags which is getting me a bit more publicity.
(By the way, i'm not doing YouTube for the fame, I'm doing it because I've been playing games since i was a young child, and thought that some of the stuff i do it funny. It is in no way associated with money or fame, I just really want to interact in gameplays with my audience. (If I ever get one)
