all about ISUSPM.exe

Windows is a far more complex ecosystem than most would think. It has several background processes, some of which often lead to 100% CPU usage or high RAM consumption. And one of the common processes that frequently leads to issues is ISUSPM.exe.

The problem is that ISUSPM.exe does not appear as an application in the Task Manager or the Control Panel, making it difficult to remove the program as a startup app or uninstall it altogether. So, let’s find out all about the process and how to fix things with it!

What is ISUSPM.exe in Windows?

ISUSPM is a process in Windows that updates the installed programs. Its primary role is to identify any newer versions of apps and automatically download them. And to achieve this, the process keeps running in the background and kick-starts as soon as you boot Windows.

For those wondering where is ISUSPM.exe stored, the executable file can be found in the following path:C:\Program Files\Common Files\InstallShield\UpdateService\ISUSPM.exe

The process comes bundled with the Windows installation, and there’s no straightforward way to remove it. Some of the problems you may encounter with ISUSPM.exe are:

  • Increased resource consumption: One of the common reasons users first come to know about ISUSPM is an increase in resource consumption, which is evident in the Task Manager.
  • Frequent application errors: Though it’s recommended that users update the installed programs, some newer versions introduce instability or bugs, which may trigger application errors or make Windows crash.
  • Higher boot time: Every program added to the startup list increases the boot time, no matter how minimal the increase is.
  • Slower Internet speed: ISUSPM.exe downloads updates, which, when larger in size, can drain the network resources and lead to slower Internet speed in Windows.
