Setup Steps

Main menu

Download from GitHub as ZIP and look for the Windows Background folder.
Create a \IntuneApp\Wallpaper\wallpaper1.png
See Common Display Resolutions below for size suggestions but QHD 2560 x 1440 is a good start
These will end up in the common documents folder: C:\users\public\documents\Walllpaper
Set the Background Color and WallpaperStyle in SetDesktop.csv
Background Color=#040E4C for Dark Blue (Hex color code from www.color-hex.com)
WallpaperStyle = Fill to fill the entire screen with the image, preserving the aspect ration (AR) and cropping image as needed
Note: Fill obviates the need for Background Color; for smaller images, use Center
Test it
Double-click SetDesktop.cmd to test it
If you are scriping the installation use SetDesktop.ps1 -mode auto to automatically install the wallpaper
(Optional) For users of the IntuneApp app publishing system
Change intune_settings.csv to adjust publication audience

Settings in `SetDesktop.csv`

Open SetDesktop.csv and adjust these values

Wallpaper

wallpaper=wallpaper1.png
The filename of the wallpaper (just name, no path)
If this is left blank (or invalid) you’ll just get the background color

Common Display Resolutions

If you want to fill the entire display background, use an image (.png preferred) of this size.

Display	Resolution (H x V)	Aspect Ratio
4K	3840 x 2160	16:9
QHD *	2560 x 1440	16:9
FHD	1920 x 1060	16:9

* Recommended

WallpaperStyle

WallpaperStyle=Fill

Recommended settings

Wallpaper that fills the screen: large .png file with QHD resolution using Fill WallpaperStyle
Wallpaper showing background color: small .png using Center WallpaperStyle and BackgroundColor matching image

WallpaperStyle values

Style	Description	RegVal	Background Color may appear around edges	Image Crop may happen	Image Scale may happen	Image Aspect Ratio maintained
Fill*	Expands image to cover the screen, leaving some to hang off screen	10	N	Y	Y	Y
Fit	Shrinks image so that it can be entirely seen (letterbox)	6	Y (if AR of screen and image don’t match)	N	Y	Y
Center*	Centers the image on the screen	0	Y	Y	N	Y
Stretch	Breaks aspect ratio of image (stretches each dimension) to align image edges with screen edges.	2	N	N	Y	N
Span	Pulls the image across multiple displays	22	N	Y	Y	Y

* Recommended

Background Color

Background Color=#040E4C (for Dark Blue)

Use the hex code for the color. www.color-hex.com
If you choose the background color of your image, you will have a centered image that blends with the background.

Some standard color examples

Color	Hex
black	#000000
blue1	#000040
blue2	#040E4C
green1	#0C590C
green2	#1A241B

Settings in `intune_settings.csv` (Optional) for users of the IntuneApp app publishing system

Open \IntuneApp\intune_settings.csv and adjust these values if you are using the IntuneApp app distribution system

To make this a mandatory app (push to all users)

set PublishToOrgGroup = TRUE

To make this mandatory for new users only, but not for existing users, use this IntuneApp technique:

Publish once with PublishToOrgGroup = FALSE and CreateExcludeGroup = TRUE
This creates an app-only exclude group (ending in Exclude).
Add all current users to the app-only exclude group.
Publish again with set PublishToOrgGroup to TRUE to pubish to any future users.

If you are replacing a previously pushed background, use this IntuneApp technique to overwrite previous installs:

Change AppUninstallVersion to match the last AppVersion
If you don’t adjust this, endpoints with prior versions will not get the new wallpaper
