MUSCOVITE"He never share his car WITH his friends". I guess this is fine in all respects?

He never shares etc.

MUSCOVITE"He never shares his car TO his friends"?

"To" does not work with "shares."

"He never loans his car to his friends." This would be fine.

give to, lend to, but not share to.

Only share with.

Please take a look at the following two sentences:

1a - "Let him share desktop to the videoconference".
2a - "Participant can share desktop/application to the conference."

Both are taken from a "technical note" (presumably) written by a native speaker (or a VERY advanced ESL speaker, to my eye :-). And so my first guess was that "sharing smth to smb" was a passable alt

This may be internet speak.
The verb "to share" has taken on new meaning. ("file sharing," photos, etc.)
To share something on the internet is usually to send it to someone.

"Just a guess."

Thanks, Avangi!
The only good news for me is that MS seems to still prefer 'WITH' in similar contexts.
Following is what I just found on windows_microsoft_com:
QUOTE:

Share files with someone

Windows provides two methods for sharing files directly from your computer. You can share files from any folder on your computer, or from the Public folder

In my opinion the word "share" is being misused to mean "lend out". Some articles are missing as well, but that may be because this is in a technical note, not in the main text.
