If locking doesn’t protect your PC
Locking only helps if your account has a password or PIN. If you get straight back in without one, add one in Settings > Accounts > Sign-in options. See how to change your PIN in Windows 10.
If Windows + L does nothing, a work or school policy may block locking, or the Windows key may be turned off on a gaming keyboard.
