Windows is spying on you and most people will not even know this. When Bitlocker shows up because of some problem most will not know their microsoft account or the bitlocker key. They have now lost everything on that pc.
BTW Microsoft has a master key and can turn it over to the police etc. but they will not use it to help you get into your pc to get your files, just the police.

One response:

However, it is not [normally] automatically turned on during an upgrade from a previous version of Windows.However, Microsoft warns Windows 11 25H2, 24H2 October update triggers BitLocker recovery on PCs for businesses

To check if BitLocker is turned on your PC, open Settings > System > Storage > Disk & Volumes. Select ‘Properties’ under one of the volumes, and if it says ‘Encrypted’ under BitLocker, it means the feature is turned on.
