"Turning off Bitlocker" without choosing the decrypt option only
turns off the authentication process- encryption is still on and
all new files are encrypted also. Your restore points will not
be deleted so long as Vista stays encrypted- regardless if
Bitlocker's authentication is turned off.
Haven't encountered any problems with encryption on. You
don't notice (I haven't) anything being different. Of course,
you won't be able to see Vista from XP. It will show a drive
letter and if you click on that drive letter it will tell you that it
is an unformatted volume. Leave it alone. ;-)
I apologize, I should have told you this earlier- make sure you
print/write out the password or save it someplace other than Vista.
Some folks have reported that BitLocker is not reading the encrypt
key from some USB thumb drives. An MVP in the vista.security group
has said this will be improved by RC1. I have not experienced that
problem. If BitLocker can not read your USB drive and you don't
have your password- you are screwed. Pardon my language.
Recently, I have turned off the authentication at boot-up.
It's funny, I stopped using System Restore in XP a long time ago.
Found it to be unreliable and that it slowed down a computer. But
I wanted to really test it out this time and give it a chance. I've used
it twice and all went well. It is my understanding that SR in Vista is
much improved over XP. Of course, since I dual boot, the only way to
test SR is to protect my restore points. I just happened to stumble onto
the fact that BitLocker kept those restore points from being deleted.
There were some at Microsoft who said it wouldn't matter if BitLocker
was on and the drive was encrypted, the restore points would still be
deleted. Well, I knew what I saw. After, many tests- BitLocker does
protect the restore points- can't delete what you can't see. Which
makes perfect sense. I don't know why some said it shouldn't be
that way. I even asked specifically before I used Bitlocker if encryption
would protect those restore points, I was told no. Trust me, it works.
Let me/us know how it turns out.
Take care,
Michael
