    What is sppextcomobj.exe?


    I have a process running called SppExtComObj.Exe. I searched it and found only a vague discription:

    sppextcomobj.exe executes as a process with minimal NETWORK SERVICE privileges. The assembly utilizes the .NET run-time framework (which is required to be installed on the PC). This version is installed on Windows 8 and is compiled as a 64 bit program.

    Does anyone have any information on this? What is it for and why do I need it?

    I can only tell you that I have it on my Win 8 machine, it appears to be a legitimate part of the OS, and I think it might have something to do with KMS Licensing for Microsoft Products (like MS office) but I'm not sure because I do not have any MS Office products on my machine. Good luck.

    I think you might be right. I dug a little deeper and found that it is for licensing - Key Management Service (KMS) Microsoft Volume Licensing - Product Activation
    Thank you for your help!
