A new 64-bit workstation running Windows 7 at first had the usual icons for MS Office 2010 Word, Excel, Access, and Outlook. The icons on the taskbar for Word, Excel, and Access almost immediately morphed into the same generic icon. The generic icon doesn't show the program name so I need to hoover each icon to see which program it represents. The same generic icon appears in the START menu just for Word, Excel, and Access.The Outlook icon remained normal on both the taskbar and in the Start menu. All other components of the MS Office Suite 2010, which weren't yet on the taskbar, have normal icons in the Start menu. I don't want to pin them to the taskbar now, as I'm afraid they'll all morph too!
This happened the day the workstation was installed and I attributed it to changes I made to the desktop wallpaper and screensaver. I doodled around and got the normal icons back, only to have the generic icon reappear a week later. And this time, I wasn't working at all with the desktop wallpaper or screensaver.
Any idea what causes this?
