What exactly is an “app” on Windows?

It sounds like you've hit a tough spot with those bluescreens! First off, check your minidump files; they can really help pinpoint what's causing the issue. And yes, you're right—Microsoft calls programs 'apps' nowadays. They usually mean software you can install from the Windows Store or elsewhere on your computer.

In Windows speak, an 'app' is just shorthand for 'application.' Most Windows crashes tend to link back to driver issues, so keep that in mind! Just remember, when resetting Windows, your personal files should stay safe, but those downloaded programs might not.

To answer your question, 'app' equals application, and that's what Microsoft calls them now. A reset keeps your personal stuff but can remove installed apps. If you're feeling adventurous, you might want to check if you can use the Performance Monitor (just hit WIN+R and type perfmon.exe /rel) to see recent crashes.

Apps are essentially just the modern term for software you install on your computer. As for the reset feature, a clean install is often a better choice than a reset if you want to avoid potential problems. It's known that the reset can be iffy and might lead to more headaches.
