An update for Windows is rendering many older game discs unusuable
Microsoft has released a security update for Microsoft Vista 7 and 8 that will stop game discs that use Safedisc DRM from working.
This was already the case for Windows 10, which also doesn't support discs running SecuROM, but these games were previously still usable on systems running older versions of Windows.
It has been a while since games have used this form of DRM, but still could present a problem for anyone with a large collection of PC game discs they'd like to keep using.
There is a way around this, though, if you want to run a game that isn't working. The method is outlined on Microsoft's support page for the update.
