Options for displaying Powerpoint Presentations that don't require a Microsoft account?

Good morning folks,

Im in the process of setting up a PC for a TV going into one of our break rooms. It will auto-login to a generic account (without any licenses) and it's main usage will be to display the occasional Powerpoint from a few users. Powerpoint Viewer is no longer available for download, and the alternative (provided by MS) is to use the Web version of PPT(which requires a MS account being logged in). Are there any other options that you guys vouch for that doesn't require any sort of login to use?
