There was recently a security update by Microsoft implemented for Windows 7, 8 and 10 that completely destroys native compatibility with a very large handful of old games, namely anything with SafeDisc or SecuROM write protection built in. I spent quite a bit of time trying to figure out why my eBay-bought version of American McGee's Alice didn't run under any compatibility settings because no one seemed to have the same issue as I did. Obviously I wasn't aware of the security patch, or even that this game released in 2000 would have copy protection that could be broken by a Windows update. I was able to fix it after a LOT of searching (and I'm pretty tech-savvy), and even then I think I was pretty lucky to have stumbled upon the solution.
Needless to say, this silent patch is going to confuse the heck out of a lot of gamers when their old CD-based games just don't launch and there's seemingly no answer to why. So my question is: should I post a question and answer on this site detailing what is wrong and how to fix it? Should I include an abbreviated list of popular affected games? As it affects a substantial number of games, what should I title the question, and what should I tag it with?
EDIT: I have now posted this question. Thanks for your help!
