As an alternative to the bloated and AI-interrupting PDF readers from Microsoft and Adobe, the SumatraPDF is a streamlined and free PDF viewer from Microsoft Windows.
Download the latest Sumatra PDF release.
Most Windows users will likely choose the "Installer" so it integrates with the Start menu and file name extensions. The "Portable version" is a self-contained program that simply runs.
After download, run the installer.
I usually choose Options for making files searchable and for preview.
I prefer to not have the "Home" blank page, so I disable that in the Menu -> Settings -> Advanced Option. In the configuration file change item "NoHomeTab" from "false" to "true". Save the configuration file and restart Sumatra PDF.
