Can screen saver settings cause my screen to lock?

This setting is usually enabled by default and is almost always easily configurable from the System Preferences or Control Panel menus.

Is it safe to change screen saver settings on my PC?

Changing your screen-saver settings is generally safe if you choose a reputable provider. It’s important to note that some third-party screen savers can contain malicious code and software, so it’s essential that you only download from trustworthy sources.

Can I change my screen saver when I open Windows settings?

Yes, you can change your screen saver when you open Windows Settings. To do so, navigate to the Personalization tab in Settings and select “Lock Screen” from the options on the left-hand side. Here, you’ll have access to various settings, including setting a new screen saver and any desired customization options.

Why can’t I disable lock screen on my PC?
