Program for activating an illegal Microsoft office 2010 version
KMService is server application which is run on stand-alone computers to enable the Volume License edition of MS Office 2010 to run continuously without the need fo re-activation every 180 days. If the computer were part of a network then the KM Service running on the server keeps Ofice 2010 activated on all connected machines..
Used for pirating MS Office 2010 - may be legit on enterprise machines.

This services is not used for just Microsoft Office 2010. It is also used for Office 2010, 2013 and 2016 but I also can activate MS Windwos 8, 8.1 ot 10. It is used not just for Micrsoft there are other software companies / Brands / Aplication it is used for to CRACK or Pirate the software so you can use it for free to extending the trial period to give more time to learn it. The biggest question is simple did you install software on your PC that to use it - You had to do extra setups to activate it - IF yes then your safe and if no then maybe not!

Best practices for resolving KMService issues

A clean and tidy computer is the key requirement for avoiding problems with KMService. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
