The SppExtComObjPatcher.exe (also called AutoKMS) is an executable that is located in the C:\Windows\System32 or C:\Windows\Setup\scriptsx64 directory. This process may seem as a part of the Windows operating system and some users may find it running in the background.

In spite of technically looking like a system file, however, the SppExtComObjPatcher.exe is not an executable from Microsoft but a file that is often ran by program activators. In other words, if you are using a cracked Windows or MS Office version or you have used a software activator to unlock its full license, then this is the reason why you may detect the SppExtComObjPatcher.exe process running in your OS.

SppExtComObjPatcher.exe is a background process that runs in pirated version of Windows or MS Office.

Some users may be okay with the use of pirated Microsoft software versions, but others may be victims of such software without knowing it. That’s why, the SppExtComObjPatcher.exe process should always be treated with care because is it perfectly possible that it may be part of some malware, which logs and sends collected information to people with malicious intentions.

Fortunately, most anti-virus programs can detect that the SppExtComObjPatcher.exe process is not originally part of the Windows OS and suggest actions to eliminate it. However, users should keep in mind that many crack instruments and software activators may have the ability to exclude themselves and their files from being scanned by anti-virus programs and in this way they can make room for malware-like behavior. In other instances, the users may deliberately allow the SppExtComObjPatcher.exe executable to run on their machine.

SppExtComObjPatcher.exe may get into your Windows PC in several ways:

  • You have deliberately installed it. Many web users intentionally install cracked software to bypass legal applications’ licensing measures. In this way they can use a given software free of charge, but at the same time this comes at the cost of serious security risks, not to mention that it is illegal.
  • You have purchased a machine with already installed Windows copy on it. Sadly, there are shady retailers that can install a cracked version of Windows on your computer and even request extra money for this which is a very unethical practice.
  • SppExtComObjPatcher.exe has been mounted on the computer through some malware. Advanced malicious programs may install different files and executables inside the system they have compromised and very often they may disguise them under file names that are common and won’t drag much attention. However, there is no guarantee about the safety of SppExtComObjPatcher.exe even if the file has been installed by you.  

At the same time, many users question if SppExtComObjPatcher.exe is really that dangerous, as they take into account the fact that many antivirus providers may flag the file because they don’t want to encourage pirate usage in general. While this might be true, after all, the job of security software vendors is to protect users from any potentially malicious or illegal file and so they initiate the SppExtComObjPatcher.exe removal as soon as it has been installed.

Moreover, when people use cracks and illegal software activators there may be many hazards that may be invisible.  For instance, aside from executable files like the SppExtComObjPatcher.exe, Trojans are some of the threats that can sneak inside the machine with the help of such tools and they can run in the background of the system without symptoms of any kind until security software flags them. That’s why, security experts advise users to remove program cracking tools and any related components and files such as SppExtComObjPatcher.exe, Wup.exe and Cloudnet from their computer in order to avoid the risk of being compromised with malware.

How can malicious files be prevented from entering your Windows system?

Malware typically consists of multiple components and files which get placed on your system as soon as the infection is triggered. The software cracking tools also fall in the category of deceptive programs because, apart from being illegal, they can run different background processes, install additional files and components and make adjustments that may be invisible for you.

And while they may perform the intended functionality (namely to bypass the software’s license protection) they may also be able to inject malicious components into the system that secretly collect information, such as login credentials, online banking details, passwords, personal correspondence, etc. Besides, there is no way of saying if the version of a cracking tool that you are using is safe because, even if there are no questionable activities, most security applications would almost always flag it simply because it is unlawful.

The following simple security tips may also help you avoid the installation of malicious executables in your system:

  • Use anti-malware software and don’t overlook its notifications.
  • Apply Windows and programs security patches as soon as they are available.
  • Provide strong passwords to protect your accounts.
  • Whenever possible, use two-factor authentication.
  • Avoid the use of cracked software and install programs only from legal and reliable developers.
  • Protect your web browser with ad-blocking and real-time web surfing security extensions.

How to remove the SppExtComObjPatcher.exe file?

While there may be many discussions, reputed security researches are united under the opinion that software cracking tools and their files and components are fundamentally unsafe and it is inadvisable to keep them in your computer. Therefore, if you are using some kind of software activator or a crack tool and you have the SppExtComObjPatcher.exe file in your Windows machine, our recommendation is to remove both the tool and the file. This can easily be done with the help of a trusted anti-virus program of your choice which can not only remove the questionable components but also scan and protect your entire computer for hidden malware.
