First of all, to make you happy, Microsoft has not removed Screen Saver from Windows 10! They have just relocated it to some other place without a icon, so it is very easy to miss it. All you have is a simple hyperlink text to get there. By default Windows 10 settings, Screen saver comes disabled. Let’s see how to enable it.
1. Click on “Action Center” icon on taskbar and then click “All Settings”.
2. Click “Personalization”.
3. Click “Lock Screen”, then scroll down to bottom of right pane and click “Screen saver settings”
4. This is where you can set the screen saver. The app is still the same old style with same features, so you should have no trouble in setting it.
