Java Quick Starter

Jqs.exe is a Windows based process used to speed up start-up time for Java applets and applications. JQS, acronym for Java Quick Starter, runs behind the scene without letting a normal user know about its actions and the corresponding reactions. Whenever a computer with Windows operating system is booted, the jqs.exe file loads into the memory with the aim of reducing time to start Java applet and applications. In case of PCs with batteries, the Jqs.exe is disabled if the PC is running on battery and resume on its own when AC power is restored. This functionality is added to the process to minimize consumption of battery.

Java Quick Starter (JQS) loads most frequently used runtime environment files into memory. Thus, whenever a Java applet or application is being executed, it finds a lot of required supporting files already loaded in memory. This pre-loading saves the time to load required start-up files into memory whenever an applet is being started. JQS was introduced for the first time in Java SE 6 update 10 release. The program performs its functionality in Windows XP and Windows 2000 and is being considered useless for the newer versions including Windows 7 and Windows Vista as these versions have their own pre-loading processes.

On one hand where Java Quick Starter provides the advantage of pre-loading the frequently used files into memory to save loading time for Java applets, it also consumes an extra amount of memory on the other hand. The Jqs.exe file and the supporting pre-loaded files occupy a certain amount of memory (maximum 20 MB), reducing the memory for remaining executions. You can destroy the Jqs.exe by opening "Processes" tab in "Task Manager" and clicking "End Task". In order to permanently disable Jqs.exe from loading in memory, follow these steps:

1. Click on "Start" button

2. Open "Control Panel"

3. Open "Java Control Panel"

4. Select "Advanced" tab

5. Move down to "Miscellaneous" option and click on "+" sign to expand

6. Uncheck "Java Quick Starter" checkbox

7. Select "OK" and reboot your system

Most of the inexperienced computer users have no idea about this process and it didn't make any difference to them as well. However, the selection to let Jqs.exe run or not is for those users who have a knowhow of memory. It's up to the user to select if he wants to vacant some memory by disabling this process or if he wants it run. Whatever it is, the process is decreasing its value as the Windows 2000 and Windows XP versions are becoming obsolete with time.
