As with similar players that don't pay the license fees to the owners of the Blu-ray spec, this player bypasses the DRM on a Blu-ray disc. That means that like Blu-ray copy & ripping apps, it will need to be updated from time to time to keep up with changes or additions to the DRM these discs use. It does not display the java menus & features on the disc. Alternatively you could use an app that copies the Blu-ray to your hard disk, removing the DRM in the process, e.g., using the prior GOTD, DVDFab Blu-ray Copy. That allows you to use a superior player like MPC-HC, which offers some display enhancements.
Apeaksoft Blu-ray Player is somewhat large for a player at ~160MB, compared to the Thundersoft Bluray Player at ~76MB, a previous GOTD, but far smaller than PowerDVD Ultra at a whopping 860MB. Surprisingly I couldn't find it offered for sale on Apeaksoft's site -- it may be something they no longer offer, or a new product they might offer in the future, or perhaps it's blocked because I'm in the US, where a company behind some of the DRM Blu-rays use successfully went after DVDFab in court. I tried the player on a fairly recent disc, "Eternals", & it appeared to work -- I say "appeared", because I would have to watch the entire movie, then compare it to watching the movie in PowerDVD Ultra... the DRM can scramble or delete scenes, as well as simply stop playing part way through. Installing the Apeaksoft Blu-ray Player did one think I don't like personally, associating the app with several types of media files, so I copied the installed app from my VM -- simply running it does not make those changes to the registry. Besides the program's folder, you get new folders in ProgramData & Users\ [UserName]\ AppData\ Local\. Other than all the file type associations, installing Apeaksoft Blu-ray Player adds one registry key for Apeaksoft, one for uninstall, & one for the activation. The GOTD readme.txt file is incorrect -- the URL to request a key should be: apeaksoft[.]com/special/gotd/blu-ray-player/?utm_source=gotd&utm_medium=blu-ray-player&utm_campaign=bd . Response was immediate & not blocked by spam filters, though it did wind up in the spam folder for 2 of 4 accounts tested.
