I'm still working on the Hotspot issue, but last night I found and
installed the Bluetooth software for windows7. There were no
instructions. I think I did it right.

Now, after installation, I have 12 .exe programs including 5 that come
with the Bluetooth logo, something like this:

|\
\|/
/|\
\/

They are
BTStackServer.exe
Bttray.exe
Btwhfconfig.exe
BtwIEProxy..exe and
Btsendto_explorer.exe

And there are 7 others without the bluetooth logo in the icon field.

Is one of them the program I should start to start Bluetooth, so that
the phone sees it.

At least some of those should be launching as services.

A desired end result, is a BT tray icon.

This is an example for the wrong OS. It shows I have no
control panel for it, but Settings wheel has a single toggle.

Whereas the Tray has a menu with more capabilities listed.

Check with Sysinternals "Autoruns" and see if there's
some item using the Bttray.exe. Your "thing" really should
have had a proper installer, not a bag of parts :-)
