[texworks] Is it possible to use texworks in a portable way?

Is it possible to use texworks in a portable way?

I'm using miktex-portable, primarily locally installed on a hard disk 
(see the configuration info below), but I also would like to use a 
second installation on a USB-Stick. Unfortunaltely miktex-texworks 
stores some information in the windows registry. 
(HKEY_CURRENT_USER\Software\MiKTeX.org\MiKTeX\2.9\TeXworks:
default-Encoding, default-Engine, font, ...)
Using one of the installations distorts the other, even lets the other 
hang during program start. After deleting the registry-entries the 
program starts again, but of course some preferences are forgotten.
