Instead of packaging those libraries into every single app (which would waste gigabytes of space), Microsoft provides the Redistributable . Your app says, "I need the 2015 runtime," and Windows checks if you have it. vc redist 2015
So if you see three different entries in your "Apps & Features" list (e.g., 2013, 2015, and 2022), don't uninstall them. They are not duplicates; they are different major versions, and old apps might specifically need the exact 2015 one. The 2015 version was revolutionary for one hidden reason: The Universal C Runtime (UCRT) . Let’s break down what it actually does, why
