Sorry, I guess I could answer this myself with a little effort, but haven't had the time to boot off a thumb drive or similar...
I enabled Bitlocker on win 10 pro. My first dealings with bitlocker. in settings-manage bitlocker- it says that bitlocker is on.
Booting up is the same as before - windows splash screen, then the normal windows login screen.
uh, I thought there'd be something before that to unlock the drive? Years ago with some 3rd party thing, you'd get a screen asking for a password before windows would start.
Beause this is a MS software, that's not the case?
Windows boots enough to ask for a password. If that fails, you won't get anywhere? If i boot from a thumb drive / linux / etc. I'll see gibberish? (other than maybe windows directory?
And I've done that hack of renaming utilman.exe with cmd.exe to be able to get to a dos prompt to get into a computer we're locked out of. Same thing - if I did that, most all of the C drive will be gibberish / not readable? But yeah, I guess you want to rename utilman.exe back to normal again, otherwise someone could make an admin account and be able to log in? And then by extension.... say I lost this laptop. Someone boots from usb, does the utilman / cmd change. creates a user... then they get to all the hard drive data? Or at least my c:\user folder is still locked? Even with linux ignoring NTFS permissions?
