absolut ungefährlich. die procexp64.exe ist ein verbesserter und erweiterter TaskManager mit tonnenweisen Infos zu geladenen Prozessen und /oder Programmen - all das, was der TaskManager alleine nicht bietet

alternativer Taskmanager jedoch eher für erfahrene Nutzer

Part of a tree created by process explorer tool. Process explorer is a malware removal tool that helps you find and shut down unwanted or dangerous programs so you can easily delete them. This program is mostly safe but can cause issues if used incorrectly.

It's a valid Sysinternals tool that can give way more information than the built in Task Manager

Best practices for resolving PROCEXP64 issues

A clean and tidy computer is the key requirement for avoiding problems with PROCEXP64. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
