I get this error when updating at work, where there are both WSUS and proxy issues that block updates. However, clicking on the bottom link of your screen shot "Check online for updates from Windows Update" is more reliable and almost always gets thru.
If you system is not connected to a WSUS server and have this problem.
Run the "System Update Readiness Tool" thsi also works for other system in the windows 7 family, for new system use DISM (Deployment Image Servicing and Management) Tool.
Make sure that the WSUS server has KB2720211 installed.
