The Windows Management Framework 3.0 Compatibility Update has been pulled from Windows Update due to compatibility issues with existing server applications, such as SharePoint 2010.
As noted on Trevor Seward’s blog, if you have installed the update and are experiencing issues, you can uninstall and reboot your server to get everything operational again.
