Hi,

1. Office Software Protection Platform Service

If your security software didn't find any virus/malware, let’s boot the computer in Safe Mode and check if issue reappears. Safe mode is a diagnostic mode that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. The words Safe Mode appear in the corners of your monitor to identify which Windows mode you’re using. You may refer to the article mentioned below to boot the computer in safe mode.

The sppsvc.exe is a Microsoft Software Protection Platform Service. This file is part of Microsoft® Windows® Operating System. Sppsvc.exe is developed by Microsoft Corporation.

If computer works fine in safe mode then try to perform clean boot and see if it brings any difference.

Putting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot.

How to perform a clean boot in Windows

Note: Refer 'How to reset the computer to start normally after clean boot troubleshooting' to reset the computer to start as normal after troubleshooting.

Do keep us updated.

Regards,

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.

4 Steps total

Step 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.

Step 2: Locate the Office Registry Key

Office Software Protection Platform Service

Microsoft stores all of the installation information for Office Products in HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice. 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

Step 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.

Step 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!

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!

  Thank you so much! Finally someone narrowed down which keys to delete! I could only recommend a general registry cleaner to others having this issue.

  Nice. Good to know exactly what to look for, when even the M$ 'fix it' doesn't get it all.

  Office 2010 is really bad about removing these keys so this is a all too common task for me!

  Thank you for this! I've started doing Office upgrades on our workstation, and it was driving me crazy that my Spiceworks inventory showed multiple versions installed on a machine when there clearly was not.

  It didn't do it for me a first. Until now...
  Solved!

  1. Disable Incremental Scanning in Settings>Network Scan. – Super Important!!!
  2. Use Microsoft fixit http://go.microsoft.com/?linkid=9669698
  3. Scan Device.
  Thanx a lot!

  Nirsoft has a free tool to retrieve the Office keys from your domain: Produkey. It has a command-line option to '...enumerate all computers in the specified domain, and load the product key information from them.'

  Get it here:
