Xtm Avengers Main 1.8 For PC is a custom Windows theme pack developed by the independent designer group "Xtm Customs." Unlike standard wallpaper slideshows, this is a full-shell transformation package. Version 1.8 specifically builds upon the events of Avengers: Endgame and Infinity War, pulling visual assets from the Marvel Cinematic Universe (MCU) to reskin almost every visible element of Windows 10 and 11.
"Main" refers to the core launcher—a central application that acts as your mission control. It replaces the standard Windows Taskbar and Start Menu with an Arc Reactor-inspired hub, complete with animated Avengers logos, character-specific sound effects (Iron Man’s repulsors, Cap’s shield clang), and dynamic weather widgets themed around the Nine Realms.
