Is it possible to hack a password-locked screen without using password guessing in windows 7?

Question

Windows

The question arose about the reliability of the screen lock with a password in windows 7. Let's say I work with a laptop at work, but then I had to go to the dining room. The laptop has important data that should not get to anyone. I lock the screen with the win + L keys, to unlock, you need to enter a password. How safe is this method of protection? How can people get my data without using password guessing? The OS itself on the laptop is encrypted with the truecrypt program, but it is encrypted only after the laptop is completely turned off, but it is inconvenient to turn on and off the computer every time, moving away from the laptop. And when you lock the screen, the data essentially remains unencrypted.

Answer 1

Since other speakers have not noticed that you are encrypting the OC partition, I will say:
Yes, using a lock is safe.
Booting from LiveCD and the standard attempt to replace executable files or edit the registry to, again, the tighter substitution of executable files, is not available if a password is required to unlock the Windows partition even when the laptop is rebooted.

Answer 2

If you left the laptop at the workplace, then your employer is in charge of its safety and this should not bother you, but if you left it somewhere else, then the only protection is Do not leave it there. The screen itself is quite reliable, but only within the framework of "while you go for coffee", but if it is compromised in this state, then having enough time left, you can hack it.
