Remove Leftover Office Registry Keys

Sometimes after uninstalling older versions of Microsoft Office some registry keys are left behind. This causes Spiceworks to think that those older versions of Office are still installed, even though the actual program files are all removed. You can follow the steps here to clean up those old registry keys so Spiceworks can get a proper inventory of the software on the machine.

NOTE: Please make a backup of Registry before making any changes to it. You can severely damage a machine if an incorrect edit is made.
1.Open up RegEdit

Open up RegEdit by going to Start>Run and typing "regedit" and pressing Enter or OK. You can also enter the "regedit" command into a Command Prompt to open up the editor.
   
2.Locate the Office Registry Key

Microsoft stores all of the installation information for Office Products in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\. Underneath this key you will see various version numbers, each corresponding to different versions of Office. They are as follows:


-9.0 is Office 2000
-10.0 is Office XP
-11.0 is Office 2003
-12.0 is Office 2007
-14.0 is Office 2010
   
Note : On a 64bit machine it is under HKLM\\SOFTWARE\\Wow6432Node\\Microsoft\\Office.

3.Locate the Corresponding Registration Key

Underneath each of the version number keys you should see a "Registration" key. Depending on how many Office products you have installed (Visio, Project, etc. all will be stored underneath one of those version keys) on the machine there will be multiple hashed keys present underneath the Registration key. Each of these hashed keys should have a value underneath it called "ProductName". You can use this value to correctly determine which hashed key is related to the product you want to remove.

   
4.Delete the Hashed Key

Once you have located the correct hashed registry key, delete it. As mentioned above, though, make sure you have a good backup before doing this!

Conclusion

Once you have performed the steps above run a scan on the device by either running a full network scan or a rescan underneath the Tools section of the device. Once the scan is complete you should see that the long deleted Office products are now gone from your Spiceworks Inventory. If the scan is still showing that the software is present, you might need to disable Incremental Scanning in Settings>Network Scan.

I hope this helps!
