How to disable Windows 10 Wallpaper compression & improve image quality


#Windows10 #Wallpaper – How to disable Windows 10 Wallpaper compression & improve image quality : Windows 10 automatically compresses your wallpaper images and reduces it to 85% of the original image quality, before setting it as your desktop background.

This helps in saving valuable disk space and improves performance to a certain extent – but compromises on the image quality. While the process is immensely useful for PCs with moderate specifications, if your system has plenty of RAM, you can disable the wallpaper compression in Windows 10. Here’s how to go about it.

Disable Windows 10 Wallpaper compression

Windows never actually applies the full quality image to the Desktop. It reduces the quality so as to enhance the system performance. Windows itself does not offer a method to disable the JPG wallpaper quality reduction in Windows 10, but a registry fix can help you disable this automatic compression feature.

If you are not aware, Windows 10 computer stores the converted image as a TranscodedWallpaper file inside the directory C:\Users\%username%\AppData\Roaming\Microsoft\Windows\Themes\. If you can manage to change its extension .jpg, you will be able to view the image used as the wallpaper.

Anyway, using this registry fix, you can disable the automatic JPEG wallpaper quality reduction feature and improve the quality of your desktop background wallpaper. To do so, press Win+R key in combination to bring up the ‘Run’ dialog box. Tye regedit and hit Enter to open the Registry Editor.

Now navigate to the following key:

HKEY_CURRENT_USER\Control Panel\Desktop

In the right pane, right-click and create a new 32-bit DWORD parameter and name it JPEGImportQuality.

The value lies between 60 and 100. The default value is  85 which means that the compression is 85%. A value of 100 indicates a very high-quality wallpaper with no compression. Set the value to 100. Click OK and exit.

Restart your computer.

Now, set the image you would like to keep as a wallpaper. It will be displayed without compression. It works in Windows 10 only. Source: thewindowsclub
