this is one of those Windows 8 [and Windows 10 now] "features" that drives me and a lot of other people nuts.
Why is it that I get different "answers", different results, different behavior, from the Control Panel "Windows Update" utility vs the PC Settings "Windows Update" utility? [And why does the latter throw an error when I press the Windows Key?] ?
dumb... I look in Control Panel/Windows Update and, for instance, will have "ready to install" a few updates - nice, clean, ready to go. I look in the Windows 8 [multi-step, slow, cumbersome] Windows Update and I have "check now"... hit the check now button, spin/spin/spin, may or may not get a response. Pressing the Windows Key to return to the relative tranquility of my desktop and it throws an error from 'Microsoft Visual C++ Runtime Library' "Runtime Error Program: C:\Windows\ImmersiveControlPanel\SystemSettings.exe" This application has requested the Runtime to terminate in an unusual way. Please contact the application's support team for more information."
