When I go to open a file (in any program) it use to show suggestions

It no longer does this.

How can I bring back that feature and what's its proper name?

At a guess, it's called "AutoComplete".

The winhelponline site thinks you currently have this situation,
which turns it off.

[HKCU\Software\Microsoft\Windows\CurrentVersion\Exp lorer\AutoComplete]
"AutoComplete In File Dialog" DWORD 0

Their registry merge file just removes the entry entirely.

I couldn't find a list of alternative values for that
entry, so you could set the DWORD to say 1 and have
the thing work again. Maybe it would work, but I don't
have documentation. It would be nicer if they just
used Booleans and were done with it.

When the item is completely missing, and there is no

"AutoComplete In File Dialog"

item, then the file dialog should autocomplete for you and
offer a small menu of matches for what you've typed so far.
