it is used the prevent windows 8 from verifying a cracked Key. Any cracked Windows8 OS needs it
AutoKMS is a keygen. It automatically executes because Office 2010 is a b*** and needs to be reactivated every time you restart the computer.

I only have it from a torrent. It is indeed malware and should be removed. I am currently in the process of attempting to rid my computer of it with repeated complication. I regret clicking immediately.
Needed to keep unlicensed copies of Office or Windows activated.
I do not know about KMS.exe

it's an activator for office 2010 and 2013.
It's needed if you installed a cracked version of Microsoft Office and/or Windows.
It prevents Windows 8 from checking a cracked key, it is not dangerous
AutoKMS.exe is a software that makes sure that Microsoft office stays registered (cracked).
Used by the Microsoft Toolkit (which isn´t actually from Microsoft) to crack Windows or Office
It is part of the Windows Toolkit (completely harmless). And you shouldnt block/delete it.
  Aris   (further information)
It will come up as dangerous and harmful because your using a program that isnt certified. It doesnt harm your PC. If you are using AutoKMS, it is because you are either using office or Windows OS cracked, the cracked files is the AutoKMS, it allows you to use the microsoft software without paying for it.
  Dont Worry

Best practices for resolving AutoKMS issues

A clean and tidy computer is the key requirement for avoiding problems with AutoKMS. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the AutoKMS.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
