This morning I noticed a lot of activity going on my PC, even at times when it was idle. I just got curious to find out what the reason could be in the strange activity on my computer. Well, like any other tech geek - I first pulled up the Windows Task Manager (hitting Ctrl Alt Del keys at once). I noticed a strange process called JQS.exe and also found that JQS.exe was running on low priority. But interestingly this strange process called JQS.exe was using 1.3 MB of computer memory and almost 2 MB of virtual memory. Also, there was a lot of activity by this process at random since it was initiating too many I/O read processes.Well, I figured out that JQS.exe was not any virus process but was indeed Java Quick Start which was actually designed to reduce the startup time of Java applets
and Java apps by prefetching Java Runtime Environment files frequently into memory and caching it. But I'm not a person who uses Java Applets or Java Apps that often - I hardly use Java related stuff maybe once in 2-3 weeks, so there is absolutely no use for it to run all the time on my box to make a rare use app work faster!!
So here is how you can easily disable JQS.exe :
- Goto the Control Panel (Start > Control Panel).
- Double click the Java icon to open the Java Control Panel.
- Now click on the Advanced option
- Goto Miscellaneous and you will find that Java Quick Start has been enabled.
- Uncheck the box to disable the JQS.exe process.
You can now see that JQS.exe has disappeared from the Task Manager.
