It is more of a Java runtime (JVM) setting than a Windows one. You configure it by adding the below parameters (example only) to your Java command line.

-XX:PermSize=256m 
-XX:MaxPermSize=512m

For example, if you were doing java -jar someapp.jar, you might have to do java -jar someapp.jar -XX:PermSize=256m -XX:MaxPermSize=512m.

A common practice is to define the -X parameters in an environment variable called JAVA_OPTS and using it in the command lines.

On unix,

export JAVA_OPTS="-XX:PermSize=256m -XX:MaxPermSize=512m"

java $JAVA_OPTS -jar someapp.jar

On Windows,

you can define a Local / System variable similarly.

java %JAVA_OPTS% -jar someapp.jar

You can increase size of PermGen Space by using JVM param -XX:MaxPermSize and -XX:PermSize.
