You're assuming that you don't have to quote a read filter.  It's an
argument to the "-R" flag, so it has to be one shell-level token, so if
it contains token separators such as spaces, it needs to be quoted.

Try

        tshark -r all.cap -w filtered.cap -R "udp contains 100"

or, if "100" has to be quoted from TShark's point of view, you'll have
to nest quotes (I don't know how that's done with the standard Windows
command line, but on UN*X shells, even if you're running them on Windows

        tshark -r all.cap -w filtered.cap -R "udp contains \"100\""

should do).
