We recently released Windows Management Framework (WMF) 5.0 RTM delivering many requested improvements and fixes, via the Microsoft Download Center as announced in a previous blog post. However, we have discovered a bug which resets the PowerShell module environment during installation. As this issue can have a serious impact on our customers, we are taking the action to stop delivery of WMF 5.0 RTM, and have removed the packages from the Download Center. Additionally, we will be unpublishing Azure DSC Extension Handler versions 2.11 and 2.12 as they automatically install WMF 5.0 RTM.
We will deliver a revised WMF package as soon as the issue can be isolated, corrected, and validated. This issue only impacts users that have installed WMF 5.0 RTM (KB3094174, KB3094175, KB3094176), and does not affect preview versions of WMF 5.0, including WMF 5.0 Production Preview. We will publish further updates regarding a new WMF package to this blog post.
Specifically, this bug resets the PSModulePath environment variable to default values, losing any changes made prior to the WMF 5.0 RTM installation. If you have already installed WMF 5.0 RTM, this issue has already affected you - we will provide guidance on moving forward to the new WMF packages as soon as we have validated a fix.
