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.

@ChrisF I want my tag and I want it now! My goal is to go down in history as the only user of Windows SUA :-) –  Mikhail Oct 29 '12 at 10:51

You should accept an answer. That of Bob is perfectly eligible –  PPC Oct 29 '12 at 15:23

Bob is a cool dude, but may be somebody has tried running software on it and something terrible happens. I am actually install the server to try to see if my "junk" still runs on it. Give me an hour or two. –  Mikhail Oct 29 '12 at 15:25

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

I like what you did there with the image and the proof. –  Mikhail Oct 29 '12 at 11:51
    
It isn't listed as a deprecated feature on the aforementioned link. –  Evan Carroll Oct 29 '12 at 17:29

Ah clearly this is either (a) photo-shopped, or (b) Windows 8 isn't ready for prime time and should be recalled en masse. Seriously, who puts out a product with buggy link-references. Microsoft can't event tell its users to RTFM properly. –  Evan Carroll Oct 29 '12 at 17:56

By "alternate methods" presumably they mean Cygwin or MinGW, which are both perfectly reasonable means of getting a reasoanble POSIXy interface that sits on top of Win32 as opposed to trying to use SUA, which IIRC were never really all that complete to begin with anyway. –  fluffy Oct 29 '12 at 19:18

@fluffy, just one problem. cygwin does not install on Win8.1. Chocolatey did not help to install it either. –  rjt Jun 14 at 7:37

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.

In theory it could be removed in the first Service Pack, we don't know if there will be a typical Windows 9, evidence points to Microsoft changing their release schedule. Visual Studio and other products are already on slightly difference schedules then in the past. –  Ramhound Oct 29 '12 at 11:42

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

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

I actually expected this reply to be incorrect, but checked on my one (so far) RTM Windows Pro install, and it is in fact correct. SUA is no longer shipped with Windows 8 Pro. –  PJC Nov 7 '12 at 12:55
    
@harrymc, cygwin does not install on Win8.1 –  rjt Jun 16 at 21:11
    
@rjt: I think this is solved in the latest version. –  harrymc Jun 17 at 6:42
