Weekend Learning: 32/64-bit OS, Internet Explorer and Excel checks

Capping our weekend learning comes some very simple version check information for the OS, Internet Explorer and Excel.  Visit My Oracle Support document "How To Check To See If IE Or Excel Is Running In 32-bit Or 64-bit Mode?" via article ID 1321637.1 to see how to check this information.  Will it be something you use tomorrow?  Probably not, but would you rather know how to check this when the time comes?  I think so!
