Only by uninstalling & reinstalling that particular app.
Please note that only apps which are fully Windows 7 - 8 - 10 compatible will give you option of installing for "All Users" or "Just you". So you could be wasting your time reinstalling them (or some of them) anyway.
Older apps won't have that option, and even some newer apps just don't bother with that option. Where that option is not presented to you at time of installation it defaults to "All users" without any feedback.
What you could do instead is just delete the relevant app shortcuts in that second account.
