(Many menu options are also blank.)
I've tried everything I can think of to fix this, short of reinstalling Windows -- System Restore to the day before the infection, this tweak from this very board, and this (not my exact problem but I thought it was worth a shot). I've even tried getting some of the files defrag uses (dfrg.msc, some of the DLLs) from a friend and putting them in place of mine, but still no go. At this point I assume it's a registry problem, but I don't want to fiddle around in there without some guidance.
Reinstalling Windows is an absolute last resort for me, as I have a lot of stuff to back up.
