You’ve come to the right place. In this post, we will be learning all about what is splwow64.exe error, why it is running on your machine, and how you can fix this error by following a few troubleshooting steps.

Let’s get started.

What is SPLWOW64.EXE

If you’re thinking that splwow64.exe is a virus, then you might be wrong.

If you dig in further to know more about this particular process in the Task Manager, it is listed as “Printer driver host for 32-bit applications”.

So, the splwow64.exe process is used for connecting 32-bit printer applications on a 64-bit Windows OS. Windows automatically triggers the splwow64.exe process when your device is using 32-bit printer drivers and the process is supposed to terminate itself as soon as the printing job is done.

In normal circumstances, no! If your device is connected to a 32-bit printer and if you see the SPLWOW64.exe running in the Task Manager, then there’s nothing to worry about. But if there’s no printer connected and if the splwow64.exe is still constantly listed in the Task Manager, then you should most certainly get rid of this process before the error creates further damage and impacts your device’s performance.
