Yeah, you had that backwards, as mentioned on the bullet below SecuROM.
Microsoft blocked the kernel driver that SafeDisc relied upon (secdrv.sys). They didn't block anything related to SecuROM (which doesn't even rely on kernel drivers to begin with, it seems).
This is not an uncommon misunderstanding either, as it all has its origin back to a Microsoft representative whom misspoke during an interview. You can see a breakdown of the whole situation here: https://www.reddit.com/r/pcgaming/comments/bt6igw/is_gog_selling_fear_with_active_securom_drm/eov1xqn/
