This problem often occurs after installing certain Windows updates, specifically KB5006670 for Windows 10 or KB5006674 for Windows 11. These updates changed how the Print Spooler service works, which can cause issues with authentication or driver installation. Other possible causes include outdated or corrupted printer drivers, incorrect registry settings, or problems with the Print Spooler service itself. Now that you know what’s behind the error, let’s look at how to fix it.
1. Uninstall Problematic Security Update
As mentioned earlier, one of the most effective ways to fix this error is to remove the security update that caused the problem. The most common culprit is KB5006670. Removing Windows updates is straightforward and is often enough to solve the issue. However, after uninstalling the update, you should temporarily pause Windows Updates. If you don’t, Windows may automatically reinstall the update, causing the problem to return.
2. Reinstall the Printer
Another reliable way to fix this error is to reinstall your printer. But before you do that, you need to clear out old printer drivers from your computer. The steps are a bit different depending on whether you use a 64-bit or a 32-bit version of Windows, but don’t worry–we’ll explain how to check and what to do. You’ll also need to restart the Print Spooler service using the Services manager.
3. Cancel Driver Installation Midway
If the previous solutions didn’t work for you, here’s another trick that has helped some users. Start by downloading the newest drivers for your printer from the manufacturer’s website. Begin installing the driver, and when the installer asks you to connect the printer using a cable, choose the option for connecting to a remote or network printer instead. Once you have set up the connection and it looks like the process is starting, cancel the installation. Now try using your printer to see if the error is fixed. While this method might sound a bit odd, it has resolved the issue for some people.
