What is JQS.exe and how do I remove or disable JQS.exe?
What is JQS.exe?
When you open the Windows Task Manager (by pressing CTRL-ALT-DEL) you might notice the process jqs.exe that is
running with a low priority. Jqs.exe uses about 1.5 Megabytes of computer memory and 2 Megabytes of virtual memory while running. It also initiates I/O processes frequent basis, if you have those columns activated in the Task Manager.
The JQS process is related to Java. Jqs.exe is the Java Quick Starter which was designed to improve the start-up time of Java applets and applications by prefetching (pre loading) Java Runtime Environment files frequently into memory. This has a benefit for mainly users who run Java applications on a day to day basis. Everyone else would probably benefit from disabling the Java Quick Starter. Think of a user who encounters one Java applet per month (or week), would it make sense to run the process all the time because of those few instances where it might start the application or applet faster? Quite inefficient!
Jqs.exe is definitely queries the Windows Registry on a regular basis. The performance increase might not be huge but you will free up some computer memory and some I/O processes on the computer system.
How to disable JQS.exe
Now, if you want to disable the Java Quick Starter process (JQS.exe) you can do that in the Windows Control Panel. Open the windows control panel and you find a Java entry there which will open the Java Control Panel.
A click on Advanced and the selection of Miscellaneous will display the activated Java Quick Starter entry. Uncheck the box to disable the process. This will be visible in the Windows Task Manager immediately.
I have no ‘Java Quick Start’ check box in the Java Control panel under advanced> settings> misc. How do I disable jqs.exe?
Do you have the latest version of Java installed? if not Try installing the latest version of java from http://www.java.com – then recheck if this option is there – If you use somthing like process explorer then you can inspect the jqs.exe process and see where the file location is ( checking it is legit)
The official disable guide here states the disable option is in version 6 ( currently version 6 is the latest)
Thanks. Just the information I was looking for.
I have the java quick start button unclicked and it still starts every time I start my computer.
Is there a registry key to disable this… we have also unchecked this option only to find that the next day it was checked again.. we need to have it permanently disabled as it is causing a lot of freezing on users computers when they log in.
You can try with (like ADMIN) : “%programfiles%Javajre6binjqs.exe -unregister” and you can do “”%programfiles%Javajre6binjqs.exe /?” to see other options & functions of JQS.exe.
Remember do that from CLI.
Greetings.
