Default JQS.Exe

JQS.Exe

If you open the Windows Task Manager 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 frequently if those columns are activated in the Task Manager.
Experienced computer users might guess that the process is related to Java and that is the case indeed. Jqs.exe is the Java Quick Starter which was designed to improve the startup time of Java apples and applications by prefetching Java Runtime Environment files frequently into memory. Thatís mainly interesting for users who work with Java on a day to day basis. Everyone else might be better of 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?
Jqs.exe is definitely querying the Windows Registry for instance. The performance increase might not be huge but you will free up some computer memory and some I/O processes on the computer system.

Now, if you want to disable the Java Quick Starter process you can do that in the Windows Control Panel. 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 Qucik Starter entry. Uncheck the box to disable the process. This will be visible in the Windows Task Manager immediately.

You can enable the process again in case you would like to use it at a later time.
