In these cases, you need an application like Startup Defender. With it, you can monitor your computer as it starts up by checking the processes and applications that start with Windows. This can be very useful if you're trying to locate the source of some unusual behavior.
The list of processes also includes detailed information, like the name and location of the application, the original file name, its location in the registry, etc. Also, if you're unsure about any applications or don't recognize something, you can always look it up via Google directly from the Startup Defender interface.
