What "home screen" means and where to find it
Your home screen is the background image and layout you see when you turn on your computer or when all your open windows are closed. On Windows, it is called the desktop. On Mac, it is called the desktop as well, though Mac also uses the term wallpaper for the background image specifically. The home screen is the first thing you see, and changing it is one of the easiest ways to make your computer feel like yours.
You can change three things about your home screen: the background image (wallpaper), the color scheme, and the arrangement of icons and folders. Each takes a different path depending on whether you use Windows or Mac, and each takes less than five minutes.
Key Takeaways
- On Windows 11, right-click the desktop, select "Personalize", then choose "Background" to pick a new wallpaper from built-in options or upload your own image.
- On Mac, go to System Settings, select "Wallpaper", choose a category, and click the image you want — no restart needed.
- You can also change your color scheme (light or dark mode) and accent colors from the same settings menu on both systems.
- Moving icons and folders on your home screen works the same way on both systems: click and drag them to a new spot, and they stay where you put them.
Changing your wallpaper on Windows 11
Right-click anywhere on your desktop (the empty space, not on an icon or folder). A menu will appear. Click "Personalize" near the top. A settings window will open.
On the left side of the window, click "Background". You will see a dropdown menu that says "Personalize your background". Click it and choose "Picture". Below that, you will see a row of thumbnail images — these are built-in wallpapers that come with Windows. Click any one to preview it on your desktop. If you like it, it is already applied. If you want to use your own image instead, click "Browse" and navigate to a photo on your computer. Windows will set it as your wallpaper.
If the image is too small or too large for your screen, click the dropdown that says "Choose a fit" and pick "Fill", "Fit", "Stretch", "Tile", or "Center". "Fill" is the most common choice — it makes the image cover your entire screen without leaving gaps.
Changing your wallpaper on Mac
Click the Apple menu in the top-left corner of your screen. Select "System Settings". In the sidebar on the left, click "Wallpaper". A window will open showing categories of wallpapers: Dynamic, Still, Collections, and Photos.
Click any category to see the images inside. When you find one you like, click it once. It will explore to your desktop when ready. You do not need to restart your computer or confirm the change — it happens right away.
If you want to use a photo from your own computer, click "Photos" at the bottom of the category list. Navigate to the folder where your image is stored, click the image, and it becomes your wallpaper. You can also drag an image file directly onto the wallpaper window, and Mac will use it.
Changing your color scheme and accent colors
On Windows 11, the color scheme (light mode or dark mode) is in the same Personalize menu. Click "Colors" on the left side. You will see options for "Mode" — choose "Light", "Dark", or "Custom". Below that, you can pick an accent color that Windows will use for buttons, links, and highlights throughout your system. Click any color swatch to explore it.
On Mac, go to System Settings and click "Appearance" in the sidebar. Choose "Light", "Dark", or "Auto" (which switches based on the time of day). Below that, you can select an accent color — click any color circle to change the color of buttons and highlights in your menus and windows.
Moving icons and folders on your home screen
On both Windows and Mac, you can rearrange the icons and folders on your desktop by clicking and dragging them. Click an icon once to select it, hold the mouse button down, move your cursor to a new spot, and release. The icon will stay in its new location.
On Windows, you can also right-click the desktop and select "View" to change how icons are arranged. You can choose "Auto arrange icons" to have Windows line them up automatically, or uncheck it to place them wherever you want. You can also choose "Align icons to grid" to snap them to an invisible grid, which keeps them neat.
On Mac, right-click the desktop and select "Sort By" to organize icons by name, date modified, size, or kind. You can also drag icons to any position you want, and they will stay there until you move them again.
Using a slideshow as your wallpaper
On Windows 11, you can set your wallpaper to change automatically. In the Personalize menu, click "Background" and choose "Slideshow" from the dropdown instead of "Picture". Click "Browse" and select a folder full of images. Windows will cycle through them at an interval you choose — every 1 minute, 10 minutes, 30 minutes, 1 hour, or 1 day. This is useful if you have a folder of photos and want to see a different one each time you look at your desktop.
On Mac, you can set a dynamic wallpaper that changes throughout the day. In System Settings, click "Wallpaper" and choose "Dynamic" from the categories. These images shift color and appearance as the sun moves across the sky, matching your computer's light and dark mode schedule.
Troubleshooting common home screen problems
If your wallpaper does not appear after you select it, try restarting your computer. On Windows, you can also right-click the desktop and click "Refresh" to reload the display. On Mac, try logging out and back in: click the Apple menu, select "Log Out", and then log back in with your password.
If your wallpaper looks stretched or cut off, go back to the wallpaper settings and adjust the fit. On Windows, try "Fit" instead of "Fill" if the image is being cropped. On Mac, the system usually handles sizing automatically, but if an image looks wrong, try a different one or check that the image file itself is not corrupted.
If you cannot find the Personalize menu on Windows, make sure you are right-clicking on empty desktop space, not on an icon or the taskbar. On Mac, if System Settings does not open, try clicking the Apple menu again or restarting your computer.
Frequently Asked Questions
Can I use a photo from the internet as my wallpaper?
Yes. Right-click the image on a website, select "Save image as", and choose a folder on your computer. Then follow the steps above to set it as your wallpaper. Make sure the image is large enough for your screen — at least 1920 by 1080 pixels for most monitors — or it may look blurry or stretched.
Will changing my wallpaper slow down my computer?
No. A single wallpaper image uses very little space and has no effect on how fast your computer runs. A slideshow that cycles through many images uses slightly more power, but the difference is not noticeable on most computers.
What if I want different wallpapers on two monitors?
On Windows 11, right-click the desktop, click "Personalize", then "Background". Click "Advanced display" at the bottom. You will see options to set different wallpapers for each monitor. On Mac, you can set different wallpapers for each space (virtual desktop), but not for each physical monitor connected to the same Mac.
Can I undo a wallpaper change?
Yes. Go back to the wallpaper settings and choose a different image, or select one of the default wallpapers that came with your system. There is no "undo" button, but you can always switch back to what you had before by selecting it again.
Do I need to restart my computer after changing the wallpaper?
No. On both Windows and Mac, wallpaper changes take effect when ready. You do not need to restart, log out, or do anything else — the new image appears right away.
