Doesn't even come with an installer! Depending on whom you ask that is actually a good thing. There's already enough software which is completely portable by nature, i.e. just a directory or even single executable which you can put anywhere, but still gets shipped as an installer only. Which depending on who wrote it might or might not get rid of artefacts again. Apart from that: just like many, many other software it's easy to acquire via PowerShell's package management in which case it will even be in your PATH. If you've got everything setup it's Install-Package sysinternals. You might need Install-PackageProvider ChocolateyGet and Import-PackageProvider ChocolateyGet before that. How come it never got integrated into the main OS? I think the story goes something like 'Mark Russinovich created sysinternals, it was awesome enough for MS to embrace it, but deemed too technical and too much for power-users to be part of Windows'. A logic which is understandable in a way. Also if you opt for procexp to replace Task Manager it actually is integrated in the OS.
