These days most desktop PDF Readers offer tabbed browsing feature, which means they open PDF documents in multiple tabs in the same application window, of course, this is not the case in earlier versions (recently, SumatraPDF has added tabs support).

If you’re a user, but not a multi-tasker, who want every PDF document to open in a separate window for Adobe Acrobat Reader DC, you can deactivate the tabbed interface without switching to another PDF application, here is how.
