i am using Windows 7 build 7057. i find this release to be a bit buggy. one of the annoyances would be the disappearance of the Networking Icon in the s-Tray. i have followed all sorts of steps, ie registry tweaks/fixes/deletes. you name it i have tried it.
so i am hoping someone out there is having the same trouble or better yet had the same problem but found a working solution. it is really annoying. and yes, the Networking Icon option is grayed out so no way of making the change in the system icons settings.
PLEASE someone surprise me with a solution.
