How do I check which Windows 8.1 updates I already downloaded and installed IF I always delete all the files in the C:\Windows\SoftwareDistribution\Downloaded directory to keep my PC optimized and clean? When I run something like Windows Hotfix Downloader - it shows me available updates but it does not list any superseded ones or any that I already downloaded (and I keep my Windows up to date using the default Windows Update). I just want to make sure there are no other updates that Windows Update may not be showing that I can download to update my OS.
I'm talking about a program that would show all possible updates for my PC and highlight or label updates that I already have, so that I know now to re-download/re-install them...
