How to access NFS share from Windows 7 pro?

Everywhere I see Windows and NFS, there is a mention of some kind of subsystem of unix apps or something like this, but apparently it's not in Windows 7 pro.

So the question is: what can I do to get access to NFS share from Windows 7 Pro? What to download, from where? Is there any commercial application, or is it just some free software installation?

I came in late, but here is a real solution: (opensource)

Was researching the same thing for win7 pro and found this: http://www.trevorpott.com/?p=385

The University of Michigan NFS v 4.1 client. This is the exact same client for NFS 4.1 that Microsoft included in Windows 8. (Indeed, Microsoft funded its development.) It is located here. However, it does take a little bit of knowledge to install. I have found it easily scriptable for installs on a mass scale, and certainly not a problem for installs on my home machine. download here: http://www.citi.umich.edu/projects/nfsv4/windows/readme.html#install

I was in the same boat. There's a 3rd party tool called nfsAxe, though it's shareware. So far I've only found that, or upgrade to Enterprise or Ultimate.

I changed version from Professional to Enterprise in registry and I was able to install "Services for NFS" from Programs and Features.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion]

"EditionID"="Enterprise"

"ProductName"="Windows 7 Enterprise"

To install NFS abilities in Win7 (verified on a Win 7 Enterprise x64 install):

Control Panel > Programs and Features > Turn Windows features on or off (upper left corner) > Check 'Services for NFS' in the listing > Ok each dialog
