Hello, thank you for reaching out to Mytour. Regarding your question, here's the answer.
To lock your computer screen when not in use instead of shutting it down to save electricity, you can press the Windows key + L to lock the screen. This method is quite effective in quickly locking your computer screen when there is important information you don't want others to see, or simply when you don't want others to tamper with your computer while you're away.
To make it easier for you to perform this action, make sure your Windows account has a password set up and the Lock Screen is installed. If you haven't set up a lock screen, you can follow these steps:
Step 1: From the Desktop screen, right-click on the Desktop and select Personalization.
Step 2: On the Settings interface that appears, select Lock screen from the left column, and it will display the current lock screen corresponding to the Preview on the right.
Step 3: Here, you select the image you want to set as the lock screen background in the Background section or choose Picture in the Background section and then press Browse to find the image you like to set as the lock screen.
So, finally, you've got a customized computer lock screen as you wish. Hopefully, this article will help you find a quick way to lock your computer screen and set up your own computer lock screen. Wish you success.
