The episode has an introduction to Windows World and the war, along with the character roster.
In this episode, two new characters, Infinom and InfiPink, are introduced to the series. Windows 10 meets Infinom and thinks he wants to take over his role as the irreplaceable Windows Version. Infinom slaps Windows 10 and meets his girlfriend InfiPink. Later, at Microsoft Battle Camp, Microsoft slaps both Windows 10 and Infinom when they fight. Infinom and InfiPink have a chat and she suggests that he will make friends next time.
The episode begins with InfiPink and Infinom receiving a message from Microsoft about the battle camp. In the first battle, Infinom wins against Windows 10 easily. In the second battle, Windows 8.1 defeats Windows 8 using her "Start power" and "Tiles menu."
The episode continues with the battles. In the third battle, Windows XP wins against Windows 7 using a knife. In the fourth battle, Windows Vista defeats Windows Neptune after growing in size. Windows 95 defeats Windows 2.0 with a pixelated bomb in the fifth battle, and in the sixth battle, Windows 3.1 defeats Windows 1.0 by blasting its startup sound too loudly. InfiPink wins against Windows 3.0 by rickrolling them in the seventh battle. The final battle between Windows 98 and Windows 2000 ends with Windows 98 winning after showing negative Google search results about Windows 2000.
After winning the OS training competition, Windows 95 demands a prize from Microsoft and is eventually given a cake from the Microsoft Store. However, before they can eat it, Microsoft has to revive the dead contestants (Windows 7, 3.1, and XP) using the Data Recovery icon. The episode ends with the introduction of Linux, who plans to take over the OS world and is angry to learn that Windows 95 has won the training competition.
Infinom tells InfiPink that Windows 95 won the training, and she gives him a cake, which he saves for InfiPink. They go to the battle room, and Microsoft announces that Linux has spotted their base. Windows 2.0 mentions another OS, but he can't remember its name. Windows 3.1 reminds him that it's Apple, and they wonder where he is. Meanwhile, Apple and his team sneak into Linux's headquarters, and iPhone realizes that they are there to defeat Linux, not Microsoft. Back at the battle room, Windows Whistler, Memphis, 1.0, and 10X watch as Microsoft checks the screen and discovers that Apple and Linux are going to fight. They feel the need to prepare themselves more.
icrosoft tells the team that Apple and Linux are about to fight, and they need to defeat Linux. Apple and Linux start fighting, and Apple uses his "crash screen" move, making Linux dizzy. Windows 2000 wonders why Windows 9 is outside, and Microsoft announces that everyone has to find and defeat Linux. Windows Uranus 2027 and 2023 argue about whether Uranus is a planet, prompting Microsoft to tell them to stop arguing and get ready to go.
Microsoft and the Windows team prepare to defeat Linux. They head towards Linux's base, with Windows 3.1 and 2.0 discussing the icons that Linux had placed to stop them. Windows 2000 encounters a clone of himself, sent by Linux to replace him, but is saved by Windows ME. The team finally arrives at Linux's base and Infinom pulls InfiPink along the entrance.
Plasma returns to Linux's base with the intention of getting rid of Windows 2000, but Linux tells him to follow him as Microsoft has already entered the base. Windows Neptune, Microsoft, and Linux continue to wander around the base and Windows 3.0 notices some icons that Linux has set up to stop them. Windows 3.0 decides to run into them, but Windows 3.1 stops him and instead plays his startup sound, causing the icons to fly away. Windows 7 gets lost in the maze-like base and Windows 8 tells him to catch up with Microsoft. Linux finds the elevator leading to the roof and takes it, but he gets hit with a BSOD that Microsoft throws at him. The battle between Linux and Microsoft begins but is quickly stopped as Linux realizes that he needs more members on his team. He then runs off to find new members, which Microsoft thinks is an epic fail.
Linux sets off to find new members to defeat Microsoft, and he reminds Canaima to guard his base before leaving. Linux meets Linux Mint, who agrees to join the fight against Microsoft. Later, Linux also convinces Debian and Gentoo to join the team. Meanwhile, back at Linux's base, Windows 3.1 kicks XP to defeat the last icon, and Windows 2.0 tells them to stop fighting. When Linux returns with new members, Canaima mistakes their arrival for a cake.
