Microsoft is enabling BitLocker device encryption by default on Windows 11

This is a most excellent place for technology news and articles.
I hope it does not affect performance
If you read that article it's only slow on systems that don't have hardware acceleration, which basically isn't any system from the past half a decade at least (and definitely not anything that would have a compatible TPM)
I'm rocking a 12-year-old 3930k with BitLocker on all drives and it's perfectly fine.
