Microsoft is enabling BitLocker device encryption by default on Windows 11
(www.theverge.com)
This is a most excellent place for technology news and articles.
when it automatically enables on win11 home, it doesn't actually "enable" until you do sign-in to windows with a microsoft account so it has a place to stash the recovery key.
and, i have not had any difficulty turning the encryption off on win11 home systems.
