You probably have Logmein disabled, and may have used Services to turn off the Logmein service as well.
You don't need to turn off Logmein "service" but it it your choice.
From http://java.sun.com/....ures/jqs.html: <-- I am no longer able to find a good link to this info
"Java Quick Starter (JQS) improves the initial startup time of Java applets and applications by periodically prefetching some of the most heavily used Java Runtime Environment files into memory (occupying no more than 20Mb of RAM). Later, when Java is launched, much less disk I/O is required and as a result, startup is much faster.
JQS is enabled by default in the Windows 2000 and Windows XP operating systems running on x86 (IA-32) or compatible hardware. It is turned off in Windows Vista because Windows Vista offers its own preloading mechanisms. When fully enabled, JQS runs as a Windows service called Java Quick Starter. The Task Manager shows a jqs.exe process.
The JQS service will perform runtime checks to determine if the system is running on battery power. If so, prefetching will be suspended until AC power is restored. This scenario is most common on laptop PCs."
