Advanced system utilities to manage, troubleshoot, and diagnose Windows and Linux systems and applications.
The author of whatever article you are looking at may not be aware of the Sysinternals tools.
I have used the Sysinternals tools for decades with great success. They do not require a user to go through a normal install process. They are standalone executables and can be placed in any folder that you wish. To "uninstall" them, you just delete the file.
I put them in C:\Utils. I have also added that folder to my system path so that I can run them no matter what my current directory is.
Logonsessions.exe and its 64 bit companion are only needed if you are troubleshooting some network connectivity issue. I can't recall the last time I used it. But I use Process Monitor and Process Explorer quite frequently.
It looks like you may have accidently put a Sysinternals folder in your Pictures directory. I wouldn't put mine there, but if it makes sense to you then that's ok.
