Windows Convenience Update causing inconvenience for VMware and Microsoft App-V users!
A quick heads up. The Convenience Update for Windows 7 SP1 and Server 2008 r2 SP1 is causing issues with VMs running VMware VMXNet3 virtual network adapter type.
According to a blog post by VMware and a post by Microsoft uninstalling the update will resolve the issue. The Microsoft article goes on to talk about an issue with Microsoft App-V where virtual applications may have difficulty loading.
Recommendation in both cases is to defer pushing this update until a resolution is in place.
