BleepingComputer.com: Windows 7 Home or Windows 7 Pro and with 3 keys?

I saw Windows 7 Home Premium listed in a BestBuy circular with 3 keys for around $110. This would be good for me because I have 3 computers and would like them to all run the same OS. I would like to do networking easily between the 3.

On Amazon I see that they Have Windows 7 Professional for $176. I'm not sure if this is what I want or not. I know that a lot of XP users used XP Professional for the fact it was 64bit. I'm not sure what the advantage of Windows 7 Professional is. I don't know if this Windows 7 Pro has 3 keys either:

I do use a lot graphic software for my work, such as Photoshop, Illustrator, etc...

So...
Windows 7 Home Premium or Windows 7 Professional??


My 2nd Question is:

If I do decide to purchase Windows 7, is there a free program that will remove all my files (photos, music, word documents, etc.) and put it on an external
hard-drive for me quickly? I don't have the patience anymore to do it manually. I used to click and drag each folder or file and put
it on the icon for the other drive. Is there a better, faster way?

Hi,

Here is a comparison chart - so have a look at which features you *need* and which features you'd *like* LOL.

As for you Amazon link, it looks like that is for one licence key only and to be honest that is a very good deal for three Home Premium licence keys!

P.S. If your processor is capable then go for the 64bit version (its the same price as its 32bit counterpart), however, make sure your processor supports 64bit!
