The Spooler Subsystem App is a program that runs in the background of your computer and manages the printing process. Sometimes, you may notice that this program is taking up a lot of CPU usage, which can slow down your computer or cause it to freeze altogether. In this article, we will explore why this happens and what you can do to fix it.

What Causes High CPU Usage?

There are several reasons why the Spooler Subsystem App might be using a lot of CPU resources. One common cause is outdated or corrupted printer drivers. If you recently updated your operating system, you may need to update your printer drivers as well. Similarly, if you recently installed a new printer, make sure you download and install the latest drivers from the manufacturer's website.

Another reason why the Spooler Subsystem App may be consuming too much CPU is a print job stuck in the queue. When a print job fails for any reason, it can get stuck in the queue, causing the Spooler Subsystem App to continuously try to process it. This can lead to high CPU usage and slow performance. To fix this, you need to clear the print queue by cancelling any stuck jobs.

How to Fix High CPU Usage

Update Your Printer Drivers

The first step in fixing high CPU usage caused by the Spooler Subsystem App is to update your printer drivers. You can either do this manually by visiting the manufacturer's website and searching for the latest drivers or use a driver updater tool to automate the process. Once you have updated your printer drivers, restart your computer and see if the problem is resolved.

Clear the Print Queue

If updating your printer drivers does not fix the issue, you may need to clear the print queue. To do this, go to Start > Devices and Printers. Here, you will see a list of all the printers connected to your computer. Right-click on the printer that is causing the problem and select See what's printing.

In the next window, you will see a list of all the print jobs in the queue. If any print jobs are stuck, right-click on them and select Cancel. You can also select Cancel All Documents to clear the entire print queue. Once you have cleared the queue, restart your computer and see if the Spooler Subsystem App is still using excessive CPU resources.

Disable Print Spooler Service

If neither of these solutions works for you, you can try disabling the print spooler service. This will stop the Spooler Subsystem App from running altogether, which may solve the high CPU usage problem. To do this, go to Start > Run and type services.msc. In the Services window, look for Print Spooler and double-click it.

In the properties window, click the Stop button to stop the service. Then, set the startup type to Disabled and click OK. Restart your computer and see if the issue has been resolved. Keep in mind that if you disable the print spooler service, you will not be able to print until you re-enable the service.

Conclusion

The Spooler Subsystem App is an essential component of the Windows operating system that manages the printing process. However, sometimes it can cause high CPU usage, which can lead to slow performance and freezing. By updating your printer drivers, clearing the print queue, or disabling the print spooler service, you can fix this issue and get your computer back up to speed.
