After upgrading a PC from Office 2010 PRO to Office 2013 STD, there is still an entry for both Office 14 and Office 15 in VAMT. How can I remove the entry for Office 14? I know I can delete it but once you rediscover it picks Office 14 back up from the computer that was upgraded. VAMT is querying the computer but I can't figure out where. I searched the registry for Office 14 and removed all instances. I also ran through the manual Office 2010 removal procedures but it still exists.  If I copy and run cscript "C:\Program Files\Microsoft Office\Office14\OSPP.VBS" /dstatus from a computer that still only has Office 14 on, it does still pick up Office 14 on the computer that has been upgraded.  I really want to know where VAMT is pulling this information from so I can remove it from the upgraded computer. 

I found a solution, just run the VB script provided in the Office14 directory.

cscript c:\Program Files (x86)\Microsoft Office\Office14\ospp.vbs /unpkey:ABCDE (LAST 5 of product key)

You can get the last 5 of the key by running:

cscript c:\Program Files (x86)\Microsoft Office\Office14\ospp.vbs /dstatusall
