You might have noticed this file pop up whenever you scan for malware with your antivirus software.

You might have also notice this file lurking in the Task Manager‘s Processes tab, automatically starting at start-up.

Even though Sppextcomobjpatcher.exe looks and acts like a keylogger (possibly collecting and sending information to third parties), this file is part of the operating system of your PC. 

It appears on users’ systems after they illegally used it to activate either their Windows operating system or other Microsoft products without actually buying the software.

Needless to say, using pirated software is not the way to go. Doing so exponentially increases the risk of malware and virus infections. Not to mention that it’s illegal.

Illegal software brings only trouble to you and your devices. Read why in this quick article.


What is SppExtComObjPatcher.exe?

SppExtComObjPatcher is part of Key Management Service (KMS) Licensing for Microsoft Products.

Because this file is not natively part of a freshly bought Windows software/application, if you find this file on your PC after buying a seemingly fresh version of Windows, then it means that your copy of Windows is pirated.

But that’s not surprising since Windows activators are often plagued with malware.

The antivirus software on your PC is picking up on this .exe file because the people at Microsoft do not want pirated copies of their operating system on the market. And rightfully so.

If you are knowingly using a pirated version of Windows, then having this file run in the background of your system is totally normal.

We recommend that you avoid using pirated software from any provider, as this can leave you open to pishing, malware, keylogger, and other malware attacks.

Losing access to your files, or getting your bank account and other personal information released to other third parties will surely cause you more harm than investing in an original Windows version.


How do I remove SppExtComObjPatcher.exe from my PC?

  1. Before attempting to remove this file from your PC, please make sure to backup your important data on an external hard drive or in the cloud.
  2. Restart your computer in Safe Mode.
  3. If you already have installed an antivirus on your PC, make sure to update it, and then run an in-depth scan of your system.
  4. After you cleaned up your PC with a good malware removal tool, restart your machine in normal mode, and enjoy a spyware-free environment.

If you aren’t sure that your antivirus program is doing a good job, we recommend switching to one that is known for its premium quality and strong defense.

Your best bet is to get an antivirus that has multilayered protection and advanced AI which will constantly improve itself and detect the newest threats.
