I've been having quite a bit of trouble with windows 7 lately and one of the current main issues is some of my icons just don't appear how they should. Here is a srceenshot of my taskbar with two of the icons playing up:
They also look like this in the start menu, if it helps, those programs are windows live messenger and live mail but it also happens to iTunes and all the office programs.
I've tried simply just ending the explorer.exe process and restarting it which sometimes did work but it's not anymore. I tried deleting the icon cache from the app data - local folder but nothing worked there.
Not sure what else to try with this one so I was hoping someone could help me out.
