Missing Icons For All .exe's On System / Except Newly Installed Ones

I have: reset the icon cache, reset registry settings (perhaps regretting it now? no effect), tried IconPackager.So the problem is that I have missing icons for all .exe's on my system, except newly installed ones. I also have a problem with any folder that contains a file. (when a folder has a file in it, it shows a preview of it inside the folder: that is the icon that is messed up, the normal folder with nothing in it is fine).I replaced that icon a while ago and then tried to set it back with IconPackager, but it never reset that icon (all the rest are fine). Lastly, shortcut icons are also screwed up.I can manually reset shortcut icons by re-referencing the .exe, but not the .exe icons themselves.

I believe this may be to do with the fact that IconPackager was intended for XP or something like that, because I've readthat the way icons are linked to applications is done differently between the two OS.So, what I need is a way to, en mass, link all .exe's with their own icons that are bundled inside the .exe.Be it an app, a cmd line, whatever.I also need a way to reset that folder problem. I've tried with the Registry to no effect.
