I currently have a default set for pdf file. I want to change that to another program. I find several questions/answers here but for some reason they do not work for my system.
Recently I had success using the answer returned by AI. I'll first look at the AI answer for this.

    To change the default app for PDF files in Windows 10:

    1. Open Start and select Settings.
    2. Select Apps.
    3. Select Default apps.
    4. Under Set defaults for applications (or Set defaults by app):
      • Either type .pdf in the search box under Set a default for a file type or link type, select .pdf, then choose the program that should open PDFs.
      • Or select the app you want to use (for example, Adobe Acrobat Reader) from the list, select Manage, then change the .pdf entry to that app.

    After this, double‑clicking any PDF file will open it in the newly selected program.
