Looking at my W7 HP using CPM's Win Features screen, it shows "Internet Explorer 8" and since I'm up-to-date on all things W7HP mine is actually IE9 of course. So wondering if an old version was retained somewhere I de-selected this item, but sure enough, it uninstalled IE9 completely. Thankfully, checking it again re-installed IE9 and all's OK afaict, but this CPM window still shows "Internet Explorer 8" on it.
So next I go to Windows' Programs and Features control panel, and under its "Windows Features - Turn Windows features on or off" is properly shown "Internet Explorer 9".
A minor thing I suppose but confusing of course and apparently a bug in CPM.
