To force Microsoft Office 2010 to activate manually open a command prompt (I assume with elevated privileges):

For 32bit:

cscript “C:\Program Files (x86)\Microsoft Office\Office14\ospp.vbs” /act

For 64bit:

cscript “C:\Program Files\Microsoft Office\Office14\ospp.vbs” /act

This is assuming that you’ve given Office a product key.  I also think this will work for Office 2013 by changing the Office14 to Office15 because that same ospp.vbs script is present in my copy of Office 2013.  I’m not sure if this works for retail versions of Office.  I only deal with volume licenses in my environment.
