To change the screen saver on Windows 10/11, open Settings, go to Personalization > Lock screen, click Screen saver settings, choose a screen saver from the dropdown, customize and preview it, set the wait time, then click OK to save. 2. For macOS, open System Settings, go to Desktop & Screen Saver, switch to the Screen Saver tab, select a screen saver to preview, set the start time, and optionally configure Hot Corners. 3. Both systems allow using personal photos as screen savers, with security options to require a password on resume—enabled via "On resume, display logon screen" in Windows or Lock Screen settings in macOS. 4. Note that screen savers do not save energy on modern displays; instead, users should set the display to turn off after inactivity through Power & sleep settings in Windows or Energy Saver in macOS to conserve power.

Changing the screen saver on your computer is a simple way to personalize your desktop experience. The steps vary slightly depending on whether you're using Windows or macOS. Here’s how to do it on both systems.

For Windows 10 and Windows 11

1. Open Settings
   Click the Start menu and select Settings (gear icon), or press Windows I.

2. Go to Personalization
   In Settings, click on Personalization, then select Lock screen from the left-hand menu.

   

3. Access Screen Saver Settings
   Scroll down and click on Screen saver settings (this link is at the bottom of the Lock screen page).

4. Choose a Screen Saver
   A new window will pop up. Use the drop-down menu to select a screen saver, such as "3D Text," "Bubbles," or "Photos."

   

5. Customize and Preview

   • Click Settings to customize the selected screen saver (e.g., change the text or choose a photo folder).
   • Click Preview to see how it looks.
   • Use the Wait field to set how long the computer should be idle before the screen saver starts.

6. Apply and Save
   Click OK to save your changes.

Note: If you want the screen to turn off instead of showing a screen saver (more common on modern PCs), go back to System > Power & sleep and adjust the screen timeout there.

For macOS

macOS doesn’t use traditional screen savers in the same way, but it has a feature called Desktop & Screen Saver that serves a similar purpose.

1. Open System Settings
   Click the Apple menu and select System Settings (or System Preferences on older versions).

2. Go to Desktop & Screen Saver
   In the sidebar, click Desktop & Screen Saver.

3. Switch to Screen Saver Tab
   Click the Screen Saver tab at the top.

4. Choose a Screen Saver
   Browse the options on the left (like Flurry, Architecture, or Photos). Click one to preview it.

5. Set Start Time
   Click Start after and choose how long the computer should be idle before the screen saver starts (e.g., 5 minutes).

6. Optional: Add Hot Corners
   Click Hot Corners… in the bottom-right to set a corner of your screen to start the screen saver when you move your mouse there.

A Few Tips

• Photos as screen savers: Both Windows and macOS let you use your own photos. Make sure the folder you select contains only images you want displayed.
• Security: You can set the screen saver to require a password when it ends. In Windows, check the box that says On resume, display logon screen. On macOS, go to Lock Screen settings and set a delay (e.g., immediately after screen saver begins).
• Energy saving: Screen savers don’t save power on modern monitors. If you want to save energy, set the display to turn off after a short idle period instead.

Basically, changing the screen saver is straightforward—just know where to look in your system settings. It’s a small touch, but it can make your computer feel more like your own.
