THEREFORE, YOU WILL NEVER BE ABLE TO PLAY DRM-PROTECTED OPTICAL MEDIA BASED GAMES IN WINDOWS OPERATING SYSTEMS EVER AGAIN.
I agree with some of your points but have to admit that I've read only parts of your wall of text (rant). I agree that the decision to blacklist secdrv.sys has indeed shady sides and there are some motivations to do so.
I am pretty sure that I will be able to play DRM protected games based on optical media, even though I have to leave the official path and don't even try to bother to solve the secdrv.sys issue but to workaround the protection. That is actually a decision each has to do for his own.
Nevertheless the secdrv.sys and other DRMs aren't troubling for the first time. I can recall that I cannot even run Dune Emperor even though the disc is original and the DRM is pretty much working - but some DRM ever had issues themselves - in junction with newer Windows releases.
Imho the introduction of DRM was the worst decision publishers ever took when trying to protect their property and also it cost a lot of money (licenses and production) - while it was exploitable too easy - any time.
Nowadays optical mediums are fairly OUT. I know just a few people that bothered to buy Blueray writer to store or copy anything like we did in the past, with CDs and DVDs in masses.
I am still convinced that the responsible MS employees aren't reading this thread, so making MS more directly aware about the problem is essential.
Steam and similar platforms will hopefully not close their doors in the future. This would be more of a critical problem than this secdrv.sys issue will become ever.
I agree with Eric and MS that secdrv.sys is a kernel near driver that would not probably work with things like secure boot and UEFI. That's why the digitally signing is so essential at all.
We could blame MS for improving security thus dropping the support for this "ancient" DRM or we just thank them that they protect us from a possible exploitable driver that no regular user is even aware about it does install itself silently on your computer
- in consequence leave you with no control about it and no knowledge if it has been exploited or not.
Have you seen any user dialogue in the past that your disc is installing the driver secdrv.sys at all? At least I haven't.
p.s. Another question: If MS is blocking secdrv.sys why Rovi (Macrovision) does not offer a removal tool for the games officially? Do you really expect that there will happen a colateral financial damage in a form of raised piracy of legacy games? I doubt it.
There are sites like abandonware etc and old games that can be now played for free using VMs etc but they don't see download rates in the thousands or millions like those ridicilous Facebook games have or games within the MS Windows 8/10 store.
