To find your current desktop background in Windows 11 or 10, open File Explorer, type %AppData%\Microsoft\Windows\Themes in the address bar and copy the file named TranscodedWallpaper, which on most PCs is the copy Windows keeps of your current wallpaper, to another folder. Rename the copy with a .jpg ending and it opens like any photo.
You set a photo as your wallpaper months ago, the original is gone, and now you want it back. Slideshows, spotlight, themes and built-in pictures are covered too.
Check Which Kind of Background You Have
Where the picture lives depends on how it was set, so start in Settings. The path is the same on Windows 11 and Windows 10.
- Right-click an empty spot on the desktop and select Personalize. You can also open Start > Settings > Personalization.
- Select Background.
- Read the Personalize your background menu. It shows one of four choices: Picture, Solid color, Slideshow or Windows spotlight.
With Picture selected, you’ll also see a Recent images row with small previews. Those previews help you recognize the image, but Settings doesn’t show its file name or folder. That’s why the next sections send you to File Explorer. Microsoft’s page on changing the desktop background in Windows describes each of the four options.
| What Settings shows | Where to look first |
|---|---|
| Picture (your own photo) | The TranscodedWallpaper copy, then the folder you saved the photo in |
| Picture (a Windows image) | C:\Windows\Web\Wallpaper |
| Slideshow | The slideshow folder you picked in Settings |
| Windows spotlight | The TranscodedWallpaper copy (may work), plus the spotlight section below |
| Solid color | Nothing to recover: there is no image |
Copy the Picture Windows Keeps of Your Wallpaper
When you set a picture, Windows typically saves its own copy in a Themes folder inside your account’s AppData folder. That copy stays put even after you delete or move the original, which makes it the quickest way back to the image on screen right now.
- Press Windows + E to open File Explorer.
- Click the address bar at the top, type
%AppData%\Microsoft\Windows\Themesand press Enter. The %AppData% shortcut jumps to your account’s hidden AppData\Roaming folder, so you don’t need to turn on hidden items first. - Look for a file named TranscodedWallpaper. It has no file extension, so Windows may show a blank icon and the type “File”.
- Right-click it and select Copy (on Windows 11 this is the copy icon at the top of the menu).
- Open your Pictures folder, or any folder outside Themes, and paste. You now have a copy you can rename safely.
Work on a copy, not the file in Themes. Windows may rewrite that file the next time your background changes, and renaming it could leave the desktop blank until you set a picture again.
Inside Themes you may also see a CachedFiles folder. On many PCs it holds a sized copy with a name like CachedImage_1920_1080_POS0.jpg, where the numbers match a screen resolution. That file already ends in .jpg, so copy it out and open it directly. Not every PC has this folder. If you use a different background on each monitor, look for more than one cached file, possibly one per display.
Prefer clicking through folders? Turn on hidden items and browse C:\Users\(your name)\AppData\Roaming\Microsoft\Windows\Themes. The steps for opening the AppData folder in Windows 11 show both routes.
Turn the Copy Into a Normal Image File
The TranscodedWallpaper copy is image data without a name ending, so most apps won’t open it until you add one. You can only edit the ending if File Explorer shows extensions, which it hides by default.
- In File Explorer, select View > Show > File name extensions. More detail is in showing file extensions in Windows 10 and 11.
- Right-click your pasted copy, select Rename and type a new name ending in .jpg, such as beach-wallpaper.jpg.
- Windows warns that changing the extension might make the file unusable. Select Yes. You’re working on a copy, so nothing is lost if it fails.
- Double-click the file. It should open in Photos. If it doesn’t, try renaming the copy to .png instead.
On Windows 10, the setting is a File name extensions check box on the View tab instead.
For a refresher on the rename itself, see how to change a file extension in Windows 11.
Expect a converted copy, not the untouched original. Windows may resize or recompress the picture for your screen, so a large camera photo could come back smaller. It’s fine as a wallpaper, but for printing, keep hunting for the original as described next.
Track Down the Original Photo or Slideshow Folder
If you need full quality, the original file is worth a search. How you set the wallpaper is the best clue.
- You right-clicked a photo and chose Set as desktop background. The original was wherever you right-clicked it. Check Pictures, Downloads and Desktop first, and sort by date if you remember roughly when you made the change.
- You chose Browse in Settings. Select Browse again. The picker may open in the last folder you used, which could be where the original sits.
- You set it from the Photos app. Search Photos for the picture, then look at its file information, which on most versions shows the folder it came from.
- The photo was in OneDrive. Search your OneDrive folder in File Explorer. If you deleted the file there, OneDrive’s own recycle bin may still have it for a while.
Slideshows are easier. Microsoft’s instructions have you select a folder of images to cycle through, and that folder still holds every picture in rotation. Choose Slideshow on the Background page and the folder you picked should be listed there. To jump to a picture you liked, right-click the desktop and select Next desktop background until it returns. To use one picture full time, the steps to change the desktop background in Windows 11 cover switching from Slideshow back to Picture.
Find Windows’ Built-In Wallpapers and Theme Pictures
If the background came with Windows, it’s usually stored in the Windows folder. Paste C:\Windows\Web\Wallpaper into the File Explorer address bar. Each subfolder typically holds a set of images. Higher-resolution versions may be in C:\Windows\Web\4K\Wallpaper\Windows. Copy what you want to Pictures rather than moving or deleting anything there.
Themes you added from Settings > Personalization > Themes or the Microsoft Store usually keep their pictures in your account. Try %LocalAppData%\Microsoft\Windows\Themes, open the folder named after the theme and look for a DesktopBackground folder. Names can vary by theme. The .theme files in C:\Windows\Resources\Themes hold settings rather than pictures, so skip that folder.
If Your Background Is Windows Spotlight
Windows spotlight shows a new image from around the world every day. Microsoft’s Windows spotlight documentation notes that the default wallpaper changes to spotlight after update KB5046633 on Windows 11 and KB5048652 on Windows 10, so you may be using it without choosing it.
- Save today’s image. Try the TranscodedWallpaper copy method above while the picture you like is on screen. It may work for spotlight too, but Microsoft doesn’t say so, and the next day’s image will replace it.
- Learn what the photo shows. With spotlight on, a Learn about this picture icon may appear on the desktop. Selecting it should open information about the photo, such as where it was taken.
- Lock screen pictures are separate. Spotlight on the lock screen is set under Settings > Personalization > Lock screen, and Microsoft doesn’t document where those images are stored. The guide to setting the lock screen on Windows 11 or 10 covers the options there.
Spotlight photos are Microsoft’s content. Keeping one as your own wallpaper is the obvious use; don’t assume you can publish or sell it.
When the Folder Is Empty or the Picture Looks Wrong
- “Windows can’t find” the path. Check the spelling, including the percent signs. You can also press Windows + R, type
%AppData%, press Enter and open Microsoft > Windows > Themes. - No TranscodedWallpaper file. If Settings shows Solid color, there’s no image to save. Otherwise, set the picture again from Recent images, wait a moment and check the folder again.
- Wrong picture. Each account has its own AppData folder, so sign in to the account that shows the wallpaper you want.
- Work or school PC. An organization can set the background for you, and the image may come from a company location. Ask IT for the file.
- Blurry or cropped. That’s the converted copy at screen size. The original, if you can find it, will be sharper. If the wallpaper only looks off on screen, resizing the desktop background in Windows 11 explains the fit options.
Wallpaper File Questions
Can I get back a wallpaper I used a year ago?
Only if it’s still in Recent images or you still have the original. The Themes copy covers the current wallpaper. Selecting the older preview under Recent images should make it current, after which TranscodedWallpaper is likely to hold that picture. Once a picture drops off that row and the original is deleted, Windows has no copy to give back.
Why doesn’t TranscodedWallpaper have a file extension?
Windows doesn’t explain why, but it appears to be a working file that Windows reads directly rather than one meant for you to open. The missing ending is why double-clicking it does nothing useful. Adding .jpg to a copy tells Windows which app to open it with.
Is it safe to delete files in the Themes folder?
Leave them alone. They’re small, and removing them may blank your desktop or reset a theme. Copy what you need and close the folder.
Does this work the same way on Windows 10?
Yes. Microsoft’s background steps apply to both versions, and the folders above are the same on most Windows 10 PCs. Only the File Explorer menus differ: Windows 10 uses a ribbon with a View tab, and the Windows 11 layout is covered in how to use File Explorer in Windows 11. Microsoft ended support for Windows 10 on October 14, 2025, so it no longer gets regular security updates.
Once your copy opens in Photos, back it up somewhere other than the PC, such as OneDrive or a USB drive, so the picture survives a reset. Right-click it and choose Set as desktop background any time you want it back on screen.
