I realize if your drives are not encrypted and someone gains physical access to your computer, the contents of the drives are accessible.

My question is, if someone is in front of your computer, how secure is it from someone being able to logon. Assuming a computer is stolen, is it possible for someone to logon with hacks either software or with some inspection or alteration of the boot drive?

Can a thief logon by obtaining your password?

Are there hacks that allow someone to logon without a password?

Thanks!

If you have a good password it will take a long time to get in but he can without logon access your hard/ssd/nvme drives if not encrypted he just need to boot with a usb stick and then via command prompt enter your drives.

Yes, good point, but I was specifically wondering if someone can logon as me. There are many reasons, but for instance could someone do illicit browser searches or impersonate me in other ways? Is access to the registry any different if you are logon-ed to the account or accessing that boot drive from another computer?

While I am pondering this, can you encrypt the boot "C:" drive that allows access with just your logon password (not a separate encryption password)?

If he has not your login account details he cannot login in with your windows account and impersonate you, browser searches and registry can be accessed and read if you boot with a usb stick, in fact all data can be accessed.

If you have a TPM chip you don't need to enter the encrypted drive with a password, if you don't you will need to enter the password. Logon password and encrypting password are two different things.

Thanks! I just installed BitLocker on my C drive and it works seamless. I want to try it on my older computer too that does have Win11, but with a patched install (no TPM). I would rather not have to use 2 passwords, but would.

Like you said above someone with skills could get a lot of settings and personal info with just the drive if it's not encrypted.

There were multiple threads where end users had boot or other problems and did not remember how to access their files that were protected by bitlocker. So make sure that you record in a safe place the information.
