Editing Windows Services for UNIX (section)

==Legacy==
[[Windows Server 2003 R2]] contains most SFU components, namely Microsoft Services for Network File System (NFS), Subsystem for UNIX-based Applications (SUA, a.k.a. [[Interix]]), and Identity Management for UNIX.<ref name="MS">{{cite web|url=http://www.microsoft.com/windowsserver2003/R2/unixcomponents/default.mspx|title=Microsoft Windows Server 2003 R2 UNIX Interoperability Components|publisher=Microsoft|archive-url=https://web.archive.org/web/20050510025015/http://www.microsoft.com/windowsserver2003/R2/unixcomponents/default.mspx|archive-date=May 10, 2005|url-status=dead}}</ref> The July 2007 SFU 3.5 Security Update updated posix.exe and related files to match the SUA version.<ref>{{Cite web |url=http://www.microsoft.com/technet/security/bulletin/ms07-053.mspx |title=Microsoft Security Bulletin MS07-053 - Important : Vulnerability in Windows Services for UNIX Could Allow Elevation of Privilege (939778) |website=[[Microsoft]] |access-date=March 8, 2011 |archive-date=May 4, 2011 |archive-url=https://web.archive.org/web/20110504182859/http://www.microsoft.com/technet/security/Bulletin/MS07-053.mspx |url-status=dead}}</ref>

Unlike the SFU, the SUA version included in Windows Server 2003 R2 (and subsequent versions) has 64-bit support and allows linking of Win32 libraries to SUA applications.<ref>{{Cite web |url=http://download.microsoft.com/download/3/C/4/3C4C7C9C-AAA0-4BD4-9C14-5BA29BDD7D4C/sua.pdf |title=Open Source at Microsoft.

[[Windows Vista]] and [[Windows 7]] Enterprise and Ultimate Editions also contain the Services for Unix components, now called the Subsystem for UNIX-based applications (SUA),<ref name="technet.microsoft.com"/> and Client for NFS v3. Users must download the utilities and SDK separately. However, the server components from the SFU product line (namely Server for NFS, User Name Mapping, Server for NIS, Password Synchronization etc.) are not included<ref>{{cite web|url=http://blogs.msdn.com/sfu/archive/2007/05/01/unix-interoperability-and-windows-vista.aspx|title=UNIX Interoperability and Windows Vista|archive-url=https://web.archive.org/web/20100308114305/http://blogs.msdn.com/sfu/archive/2007/05/01/unix-interoperability-and-windows-vista.aspx|archive-date=March 8, 2010|url-status=dead|date=May 1, 2007|author=Ashish|website=Services for UNIX - Interoperability Blog, MSDN Blogs}}</ref> – these are included in Server editions of Windows (i.e. Windows Server 2008).

In [[Windows 8]], the NFS client gained krb5p ([[Kerberos 5]] with full data encryption) support. In Windows 7, Kerberos 5 was supported for authentication, but only packet integrity checking was available for data. The maximum block/buffer size was also increased from 32 KB to 1 MB in Windows 8.<ref>{{Cite web |url=http://blogs.msdn.com/b/sfu/archive/2012/08/01/client-for-nfs-in-windows-8.aspx |title=Client for NFS in Windows 8 |work=Services for UNIX - Interoperability blog |access-date=January 10, 2014 |archive-date=January 10, 2014 |archive-url=https://web.archive.org/web/20140110164101/http://blogs.msdn.com/b/sfu/archive/2012/08/01/client-for-nfs-in-windows-8.aspx |url-status=dead}}</ref>
