>>11853368 (OP)Like many have said, it fucked with your disk drive, and even burning/ripping/emulation software. Your disk drive would eventually perform worse and worse until it is kicked into slowass PIO mode and break. On top of all the bluescreens and other issues, it was also generally not uninstalled if you uninstalled the game. Microsoft basically labelled it was malware and has blocked it from running on modern Windows, which is one of the main reasons why no Starforce games work on modern Windows anymore.
I don't recall but I think it even started refusing to run if you had drive emulation software installed, I know one of the DRMs at the time did that, I think it was Starforce. Before that it would also refuse to let you launch a game off a SCSI disk drive (because emulators at the time emulated SCSI drives) unless your system had no ATA optical drives connected to it.
I recall someone in a magazine once describing it as "scorched earth", basically taking out anything on your system that could even tangentially be used for piracy just in case, even if that's not what you was using it for, and causing all sorts of problems in it's wake.
