What is splwow64.exe and Why is it Running

If you’ve ever seen the splwow64.exe process running on your computer, you may have wondered what it is and why it’s there. Here’s a quick explanation.

The splwow64.exe process is part of the Windows Print Spooler service. When you print to a printer, the print job is first sent to the print spooler, which then sends it to the printer.

The splwow64.exe process is responsible for converting the print job from a 32-bit format to a 64-bit format. This is necessary because the Windows Print Spooler service is a 64-bit process, but many printers are still using 32-bit drivers.

If you’re wondering why the splwow64.exe process is always running, even when you’re not printing, it’s because the print spooler service is set to start automatically when Windows starts.

So there you have it. The next time you see the splwow64.exe process running on your computer, you’ll know what it is and why it’s there.

Why does SPLWOW64exe crash?

SPLWOW64exe is a process that is responsible for printing to Windows-based printers and fax printers. This process is essential for some applications and games that require printing, but can often cause crashes. The main reason for this is that the process is not very stable, and is often incompatible with certain drivers and software. In some cases, simply updating your printer drivers can fix the issue. However, if the problem persists, it is likely that SPLWOW64exe is the root cause. There are a few ways to fix this problem, which are outlined below.

The first thing you can try is to update your printer drivers. As mentioned above, this is often the root cause of the problem. Simply go to your printer manufacturer’s website and download the latest drivers for your model. Once installed, restart your computer and see if the problem persists. If it does, move on to the next solution.

Another potential fix is to disable the printing spooler service. This service is responsible for managing print jobs and often causes issues with SPLWOW64exe. To disable it, open the Services window (press Windows key + R, type “services.msc” and hit Enter), find the “Print Spooler” service, right-click it and select “Properties”. In the Properties window, set the “Startup type” to “Disabled” and click “OK”. This will disable the service and hopefully fix the problem.

If neither of the above solutions work, you can try reinstalling your printer drivers. This will likely fix any driver-related issues that are causing the problem. Simply uninstall your printer drivers from the “Control Panel” and then go to your printer manufacturer’s website to download and install the latest drivers.

If you are still having issues with SPLWOW64exe crashing, you can try a third-party utility such as “Print Spooler Fixer” or “SPLWOW64 Fixer”. These utilities are designed to fix common issues with the printing spooler service. Simply download and run the utility, and follow the instructions on the screen.

If you have tried all of the above solutions and the problem persists, it is likely that there is a problem with the Windows Registry. The Registry is a database that stores all of the settings and options for your computer. Often, issues with the Registry can cause SPLWOW64exe to crash. To fix this, you can use a Registry cleaner tool to scan and fix any errors in the Registry.
