Does Windows 8 still implement POSIX?

Question

I have a few piece of junk homemade programs that use the Windows POSIX sublayer. Does Windows 8 x64 come with SUA?

Can somebody verify that it is there? All I can find is that it was "deprecated" but the news seems to be from a year or two back.

Answer 1

In the Enterprise Evaluation (essentially, a trial version of Windows 8 Enterprise RTM), SUA is still available through Windows Features, though listed as deprecated:

Answer 2

Wikipedia states that it is deprecated in Windows 8 and will be removed in Windows 8.1.

WARNING: SUA is deprecated starting with this release and will be completely removed in the next release.

Answer 3

SUA is being removed from Windows kernel. It shows as DEPRECATED which means this is probably the last version of windows which will support it.

Here is a link that suggests so. http://blogs.technet.com/b/sfu/archive/2011/10/03/installing-sua-components-on-windows-8.aspx

Answer 4

SUA is only available in Windows 8 with "premium" client SKUs (meaning Ultimate or Enterprise) or server SKUs (meaning Windows Server 2012). (More info in source.)

SUA is not available in your version of Windows 8 Professional.

You should look for alternatives such as Cygwin or UnxUtils.
A commercial alternative is MKS Toolkit

2016 Windows Subsystem for Linux Update

I don't think this will affect Windows 8, but it might be interesting for newer releases.

In 2016 a new official Linux-like API called "Windows Subsystem for Linux" was announced. It includes Linux system calls, ELF running, parts of the /proc filesystem, Bash, GCC, (TODO likely glibc?), apt-get and more: https://channel9.msdn.com/Events/Build/2016/P488 so I believe that it will allow Windows to run much, if not all, of POSIX. However, it is focused on developers / deployment instead of end users. In particular, there were no plans to allow access to the Windows GUI.
