Which Windows power option protects access to an open session without ending that session?
Answer
Lock
Explanation
### Why this is right
Lock prevents someone from using the open session until the user unlocks it. It leaves the session running, unlike Log off, Shut down, or Restart.
### The concept
A user session is the set of programs and work open under a user's account. Locking protects access without closing that work. Logging off ends the session, while shutting down powers off and restarting starts the computer again.
### The other options
- **B. Log off**: ends the user session.
- **C. Shut down**: closes the session and powers off the computer.
- **D. Restart**: closes the session and starts the computer again.
### Terms
- **Session**: a user's active sign-in and the work running under it.
### Remember
Lock keeps the session open; log off ends it.
