Continuing with the approach of regular updates to PowerShell V5, the PowerShell team yesterday published a new version. You can read about the version in the PowerShell team Blog: http://blogs.msdn.com/b/powershell/archive/2015/02/18/windows-management-framework-5-0-preview-february-2015-is-now-available.aspx.
The download can be found at the Microsoft Download center: http://www.microsoft.com/en-us/download/details.aspx?id=45883. As noted in the team blog – this new version is only installable on Server 2012, Server 2012 R2 and Windows 8.1. I will also try it out on my latest build of Windows 10 and will report back once I get a chance to try it.
The download site has three .MSU files (one for each of the OS's mentioned) plus a set of release notes. Be careful as the file names are names of the update file are similar! The download is not overly big (circa 10mb for each msu) and takes but a minute or so to install. But, since I had an earlier preview version loaded, the installation required a reboot.
