securityhealthservice.exe close processes

Hello Mateusz Dudkiewicz,

Good to see you in Microsoft Community.

Firstly, could you let me know the specific system version? You can check it by pressing the Win key + R key, and typing "winver", then press Enter, please take a screenshot/photo of it, and only send the relevant information without PII in the next reply.

Did this occur recently, or has it been going on for a while? If it was recent, did you have any special actions (such as installing system updates, hardware changes, etc.) before that?

The securityhealthservice.exe is a legitimate Windows process related to the Windows Security Center service, responsible for monitoring and maintaining the security of your system.

You mentioned "securityhealthservice.exe its killing my processes", could you please describe it in detail or send me a screenshot/photo of it, and include it in the next reply to help me understand your situation better?

If your process is blocked and deleted by securityhealthservice.exe (or Windows Security) and you confirm the security of the process, you can allow the process to run in Windows Security.

You may Perform a clean boot (microsoft.com) to see if the process will be killed, this is a troubleshooting step. In this mode, we can further confirm whether it is caused by system problem or third-party software or personalized settings. So, please be patient.

Disclaimer: A “clean boot” starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background program is interfering with your game or program and to isolate the cause of a problem.

These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step so that it will help you get you back on track.

If anything is unclear, please do not hesitate to let me know.
