Java "user.home" property

I was working on a Grails project, and noticed very poor perfomance of resolving the dependencies - no less than 5 seconds. My colleagues got this phase working at least 5 times faster!
After little investigation i've found out that problem was with Java "user.home" system property, pointing to the network path.
This situation causes even more troubles, as all the apps which use Java "user.home" create their ".something/" in the path, specified by this property. And after that they all work very slow because of network latency.
I've found a fix here:

Basically, altering

CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Desktop

value to  

%userprofile%\Desktop 

solved the problem.
Cool!
