Microsoft has updated its family filters to block some rival browsers and says it's done so to think of the children.
The changes are part of its bid to end the compatibility clashes caused when non-Microsoft browser barons push updates, breaking the restrictive Windows 10 family settings.
The Reg understands that clashes allowed Chrome, Firefox, and others to access blocked sites.
But Microsoft's not named the browsers kids won't be able to run any more, saying only that "Most commonly used browsers don't have web filtering.
To keep your children safer, we'll automatically block these browsers on their devices."
Microsoft previously recommended parents make the Internet even more miserable by blocking the world's most popular browser and grounding their kids to Redmond's IE and Edge offerings.
