What Is jusched.exe, Uses, Common Errors & How to Fix it?

The jusched.exe process belongs to the Java Update tool and is not a malware of virus. Although sometimes jusched.exe shows an error message or corrupt and in that case you may consider to uninstall it. Here, I will provide detailed information about what is Jusched.exe, uses, file size, location, common errors, and how to fix it.

It is an application component of Java Update for Java Runtime Environment (JRE) on the Windows operating system. JRE is a software layer that runs in the background of your Windows operating system and provides the class libraries and resources so that your PC can run Java programs. Java was developed at Sun Microsystems and later handed over to Oracle Corp. 

The full form of JuSched is Java Update Scheduler.

Java Runtime Environment is immensely popular among household and office computers and today. I will be covering the Jusched.exe in detail along with some very easy methods to solve issues related to it.

What is Jusched.exe and what are its uses?

Jusched.exe is a background process and a startup item too. It is an important part of the Java Platform SE Auto updater component of JRE. As the name suggests, Java Update Scheduler checks for JRE updates and schedules them to install it on your PC automatically. You can also configure the functionality of JuSched from Java settings.

File Size & Location

In most of the cases, the jusched is located under “C:\Program Files (x86)\Common Files\Java\Java Update” folder if it was installed in Windows 10 or 8 or 7 PC. Whereas the average file size is approx 693 KB and it might vary depending on Java versions.

Is Jusched.exe safe?

The genuine Jusched.exe is completely safe and trustworthy. It is published by the trusted software giant Oracle Corporation and has a valid Oracle America, Inc. digital certificate. If you use Java programs on your PC, this file should not be removed as it is a very essential component of Java.

However, as Jusched.exe is an executable and a background process, it might be possible that it is a trojan virus and can harm your system. To confirm this:

• Check the file location: Right-click on the Jusched.exe process in the task manager and click on ‘open file location’, if the location is not C:\Program Files (x86)\Common Files\Java\Java Update, then it is a virus.
• Righ-click on the file then go to its Properties: In the Digital signatures tab, check if the file is signed by a trusted signer or not. If the digital sign is absent, the file is not genuine and most probably a virus.

Common Errors

The most common message that you may see in your Windows 10 system is the Jusched.exe application error, that will show below message:

“The instruction at <memory address> referenced memory at <memory address>. The memory could not be written. Click on OK to terminate the program.”

Causes of this error:

• Corrupted Java update files (specifically Jusched.exe)
• Jusched.exe is a trojan virus or malware

Jusched.exe consuming a huge amount of memory and CPU resources: Sometimes the Jusched.exe process is using more than 80% CPU and a lot of RAM. This implies that this file could be a malware running process such as a bitcoin miner.

Follow the steps below to fix these issues.
