Which Windows 7 version should be installed?

Hi,
I have a friend that has difficulty in selecting a version.He/She is going to use it for virtual machines in VMware Workstation,writing and editing in Office 2013,creating videos with Movie Maker and experimenting with OS ISOs.He/She has the same computer as me.Which one would you recommend?

I'd think the best choice would be Ultimate, has all the features Windows offers. The Enterprise version may work but that's for folks that have to have many computers such as businesses.

How much does it cost?
I think the Ultimate version is very expensive,isn't it?

No,he/she wants to install 7 in the physical machine.

It probably will be between $125 and $200 USD IF it can be found, no new production of the discs so will be limited to stock on hand. I'd look at Discount Software - Microsoft Office, Windows, Adobe, and More, DirectDeals.com or Amazon. Might find a copy on eBay but do be careful they are not pirated copies.

Since I know Professional is a version that almost includes everything,how much does Professional cost?
He/She doesn't need BitLocker or AppLocker,just our native language to be installed,if a Greek DVD isn't found.

I found Home Premium in a famous site in our country,for 100 euros.I have an Ultimate x64 DVD with Greek inside.I read some directions on how someone can install all of the versions from the DVD.Shall I create an ISO with ei.cfg deleted,so as to install Home Premium?
