Windows Spooler Subsystem App Stopped Working Fix

The "...Spooler Subsystem App Stopped Working..." error is a printer error message that is common on computers running on Windows. The computer spurs this error message when the printer driver is corrupt. There could be other variants of the error message. You can come across an error message like this:

"Faulting application spoolsv.exe, version 6.0.6000.16386, time stamp"

"0x4549b734, faulting module localspl.dll, version 6.0.6000.16386, time stamp"

"0x4549bcf7, exception code 0xc0000005, fault offset 0x00070a15, process id"

"0x5e8, application start time 0x01c753cf82366c15."

Below are some methods you could try to fix the problem. We are going to start from the simplest and end with the more difficult method. Let's get started.

Method 1 (Recommended for all users)

This method is the easier of the two. You should try this method before moving to the second method and method 2 should only be tried if the problem persists. Please note that it is common for there to be a repeat after using this method for the first and second time. You should only try the second method after more than three repeats. Ok, let's move on.

First, you have to download a tool from Microsoft official website called FIX IT. Go to to find this tool.

Use the tool to search for the spooler error on your screen.

FIT IT will now download a patch that will help you fix the problem. Accept the download if prompted and run it on your computer.

Method 2 (for advanced users)

The second method is a pretty simple one, and hopefully this will work if method 1 did not. First, go to Google and type in the name of your printer and then the word driver. For example, "HP inkjet 3000 driver". Next, download and install the latest driver for your printer from the manufacturer's website. Restart your computer and see if the problem is fixed.

Method 3 (for advanced users)

In this method, we are going to edit the registry of your computer. The aim here is to remove those entries that were created by the now corrupt printer driver. It is highly recommended that you make a backup of the registry before editing.

  • Click on Start located on the bottom left hand side of your computer screen.
  • Next, click on "Run", type in "Regedit" and hit on "OK".
  • Locate and click on the link "HKEY_LOCAL_MACHINE -> SYSTEM"
  • Go to ControlSet001
  • Click on Control and
  • Click on Print
  • Next, click on Environments
  • Locate and click on Windows NT x86. You are almost there.
  • Click on Drivers
  • Lastly, click on Version -3
  • Now, carefully look for entries bearing the name of the printer, right-click on the first one, follow the drop down menu and click delete. Do the same for all entries pointing to the printer.
  • Next, you must start the printer spooler with the printer connected to your computer to install the printer drivers again.
