You can simply ignore that. Anyway, this looks very strange: I've never seen Skype proposed by Windows Update.
You can download and run the System Update Readiness Tool (http://windows.microsoft.com/en-us/windows7/What-is-the-System-Update-Readiness-Tool) to resolve any inconsistency in the Windows Update catalog.
