wallmosphere-core.zip — the update package. The launcher fetches this on its own; you only need it to update by hand. 9.8 MB

What it needs

  • Windows 10 build 19045, or Windows 11
  • A 64-bit processor and a Direct3D 12 GPU
  • About 200 MB of disk
  • No administrator rights, and no account

Windows will warn you.

The installer is not code-signed, so SmartScreen shows an unknown-publisher dialog. Choose More info, then Run anyway — or check the sha256 above against the file you downloaded first.

Installing

  1. Run the installer

    It writes to %LOCALAPPDATA%\Wallmosphere and registers the wallmosphere:// handler for your account only.

  2. Choose whether it starts with Windows

    One checkbox, and you can change it later from the tray menu.

  3. Pick a theme

    BlueCat is installed with the app. Everything else is one click from the catalogue.

What happens on the first run

Splash Five seconds

The launcher opens and asks the release feed whether anything is newer.

Update Only if needed

A newer build is downloaded, its sha256 verified, and the current pointer switched. If the network is down it starts what you already have.

Desktop Takes over

The wallpaper starts rendering, the taskbar hides, the bar appears and the cursors are swapped.

What changed in 0.2.2

Wallmosphere 0.2.2 - wallpaper widgets (clock, now playing, text), AuraHeart theme, signed updates (launcher now requires a valid Ed25519 signature), security fixes.
