Hi Tiemo,

Please note that this goes against security best practice.  
Configuration files that are readable by all users should only be 
writable to privileged users, i.e. administrators.  If all users can 
read and write a single configuration file, this is very often an 
exploitable security flaw.

If at all possible, I recommend to design your software so that each 
user gets his or her own configuration file.  The "virtualisation" that 
you are complaining about is actually a security *feature* in Windows in 
order to work around flaws in older software that attempts to use a 
single, "all users" configuration file!
