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.
