How to personalize the look and feel of Windows 11
Change how Windows 11 looks from Settings and Personalization: themes, dark mode, accent colors, wallpaper, the lock screen, Start, and the taskbar.
Nearly everything about how Windows 11 looks lives in one place: Settings > Personalization. From there you can switch on dark mode, pick an accent color, set a wallpaper or slideshow, and reshape the Start menu and taskbar to match how you work. Here is what each control does and exactly where to find it.
| What you want to change | Where to find it |
|---|---|
| Whole look (theme) | Settings > Personalization > Themes |
| Dark mode and accent color | Settings > Personalization > Colors |
| Desktop wallpaper | Settings > Personalization > Background |
| Lock screen | Settings > Personalization > Lock screen |
| Start menu | Settings > Personalization > Start |
| Taskbar | Settings > Personalization > Taskbar |
| Snap layouts | Settings > System > Multitasking |
| Interface size (scale) | Settings > System > Display |
| Fonts | Settings > Personalization > Fonts |
Start with a theme
A theme is the fastest way to change the whole look at once. In Windows 11, a theme bundles a desktop background, window colors, sounds, and a mouse cursor into one saved package. Open Settings > Personalization > Themes, pick one of the built-in themes, or select Browse themes to download more from the Microsoft Store. Once the background, colors, sounds, and cursor look the way you want, select Save and name the theme so you can switch back to it later. High-resolution wallpaper packs can use real disk space, so it is worth knowing how to free up space on Windows 11 if your drive gets tight.
Choose a mode, accent color, and transparency
Dark mode and accent colors both live under Settings > Personalization > Colors. Use Choose your mode to switch between Light, Dark, and Custom. Custom lets you mix the two, such as a dark taskbar with lighter app windows. For the accent color, set it to Automatic to let Windows pull a shade from your wallpaper, or Manual to choose your own from the swatches or a custom value. Microsoft Support notes that the accent color can also appear on the Start menu, taskbar, and title bars, though the Start and taskbar tint applies only in Dark or Custom mode. The same page has a Transparency effects toggle for the acrylic blur behind menus. If that blur makes an older machine feel heavy, turning it off is one of the quick wins covered in why your Windows PC feels slow.
Set your wallpaper and lock screen
The desktop background is under Settings > Personalization > Background. Personalize your background offers Picture, Solid color, Slideshow, or Windows spotlight, which rotates a fresh Microsoft image each day. For a single photo, choose Picture and set a fit — Fill, Fit, Stretch, Tile, or Center — so the image sits right on your screen. For a rotating set, choose Slideshow and point it at a folder of images. The lock screen has its own page at Settings > Personalization > Lock screen, with the same Windows spotlight, Picture, and Slideshow choices plus a status option that shows details from an app you pick, according to Microsoft Support.
Reshape Start, the taskbar, and widgets
Settings > Personalization > Start controls the menu. Pin an app by right-clicking it and choosing Pin to Start, and use the Folders section to add shortcuts, like Settings or File Explorer, next to the power button. Settings > Personalization > Taskbar handles the bar itself: under Taskbar behaviors you can set Taskbar alignment to Center or Left and turn on Automatically hide the taskbar, and under Taskbar items you can hide Search, Task view, or Widgets. The widgets board still opens with Windows key + W even if you hide its button. To tile windows, hover the maximize button or press Windows key + Z for Snap layouts; the master switch is Snap windows under Settings > System > Multitasking.
Get text and windows the right size
If the whole interface looks too small or too large, that is a display setting rather than a theme. Go to Settings > System > Display and change Scale to make everything — text, icons, and apps — bigger or smaller together; Windows recommends the marked value for your screen. To resize text on its own, use the slider at Settings > Accessibility > Text size. To add a downloaded font, open Settings > Personalization > Fonts and drag the font file into the window, or install one from the Microsoft Store. These changes apply system-wide, so a single adjustment carries across your apps.
Everything above uses built-in Windows settings, which is the safe path. Third-party skinning tools that patch system files to restyle the taskbar or window borders can go further, but they tend to break after a Windows update and can leave the interface unstable, so back up first and expect to reapply or reinstall them after major updates. If you are still on the older release, these paths differ there — see what to do now that Windows 10 support has ended before you spend much time customizing it.
