Java Quick Starter
Java Quick Starter (JQS) improves initial startup time for most Java applets and applications. This feature was added to Java in release Java SE 6 update 10 (6u10) and will be available in all future releases.
JQS is enabled by default in Windows XP and Windows 2000 operating systems and is not necessary on Windows Vista as Vista offers its own pre-loading mechanisms. A process called jqs.exe will run in the background in order to allow quick startup. jqs.exe will be loaded after a Windows restart. Instructions on how to disable the JQS and the jqs.exe process are below.
The startup performance improvement is achieved by periodically pre-fetching some of the most heavily used Java files into memory (occupying no more than 20Mb of RAM). Later, when Java is launched, much less disk I/O is required which makes startup much snappier and noticeably faster.
How to Remove Java Quick Starter
Steps to disable Java Quick Starter:
- Click Start.
- Click Control Panel.
- Double click on Java Control Panel.

To remove, you can uninstall Java SE 6.
You can search for and delete jqs.exe which is located at the following patch on Windows XP under a typical installation.

Make sure you kill the process in Windows Task Manager first if you intend on deleting the executable jqs.exe.
