Colors of Contextmenu Automaticupdater

Hello,

i'm using the automaticupdater inside an wpf application and would like to know, if it is possible to change the colors of the contextmenu of the automaticupdater (where "update now" or "changes in version" will be displayed).

Unfortunately, i have to use also the expressiondark theme from microsoft and with this installed, the contextmenu will display it's entries in withe color over a beige background. So you nearly can't see them

Best
