Sysinternals Process Explorer 17.06 is last working final version for Windows 7

v17.07 no longer works on Windows 7.  You'll get the following error

---------------------------
procexp64.exe - Entry Point Not Found
---------------------------
The procedure entry point GetProcessInformation could not be located
in the dynamic link library KERNEL32.dll. 
---------------------------
OK   
---------------------------


Function GetProcessInformation was introduced in Windows 10 (1607), eventhougth the function definitions say's otherwise GetProcessInformation function (processthreadsapi.h) - Win32 apps | Microsoft Learn, introduced for Win8.


The processexplorer.zip contains same processes procexp.exe, 
procexp64.exe and procexp64a.exe. 

What do they do? 


File
Purpose
procexp.exeBootstrap launcher — detects OS architecture and elevation state
procexp64.exePrimary 64‑bit Process Explorer binary — the real program on 64‑bit Windows
procexp64a.exeAlternate 64‑bit binary used for DLL injection into protected processes


Why two 64‑bit binaries?

Process Explorer injects a DLL into target processes to gather handle/DLL information. On modern Windows versions with Protected Process Light (PPL) and other security boundaries, the normal binary cannot always inject into certain system processes.

So Sysinternals includes:

  • procexp64.exe → the main UI and engine

  • procexp64a.exe → an auxiliary binary used when elevated or when accessing protected processes

This is why you sometimes see both appear briefly when launching Process Explorer.


Launch most recent and correct version every time with ๐Ÿ‘‰ Clipboard Plaintext Power Tool: 20+ Power Tools ๐Ÿ˜Ž


Why drop support for Windows 7 when?

Windows OS has over 1.5 billion active users globally as of 2025, and @2.5% thus 37.5 million are still active Windows 7 users! 










Last working version on Windows 7

The last good know version to work on Windows 7 is Process Explorer v17.06 back in 28 May 2024.
