Once activated, MEMZ begins its payload, which consists of several "phases" of increasing chaos, often called "payloads":

When the computer is finally restarted—either because the user manually reset it, the system crashed from the visual overload, or the watchdog triggered a BSOD—the Windows XP boot screen never appears. Instead, the user is greeted by a black DOS-like screen featuring an animated ASCII art rendition of the infamous flying across the screen, accompanied by a harsh, 8-bit PC-speaker rendition of the Nyan Cat theme song. windows xp memz

The is a fascinating, if terrifying, look into the destructive potential of user-created software. It serves as a stark reminder of the vulnerabilities in the MBR and the chaotic, often humorous, yet destructive, side of internet culture.

Windows XP lacks the aggressive security prompts found in modern Windows versions. On XP, most users operated under a default Administrator account. This meant that when MEMZ was executed, it instantly inherited full system privileges, allowing it to modify the registry and overwrite raw disk sectors without throwing a single security warning.

Today, MEMZ is looked back upon as a milestone in tech-entertainment culture. It represents an era where malware shifted from being a purely malicious threat hidden in email attachments to a form of digital performance art. While it remains a highly destructive tool if executed on a real, unprotected machine, its legacy lives on through millions of YouTube views, Twitch streams, and the unforgettable image of Nyan Cat dancing over the digital grave of Windows XP.

The most devastating stage of MEMZ involved overwriting the Master Boot Record (MBR) with a custom payload. Upon reboot, the victim would be greeted by a message claiming the system was "trashed" by MEMZ, with no straightforward recovery method. On a modern OS, tools like Secure Boot or recovery partitions might offer protection. On Windows XP, however, the MBR was largely unprotected, and many users lacked installation media or recovery knowledge. Consequently, MEMZ effectively bricked countless unsuspecting virtual machines and real PCs, often during pranks or poorly labeled "screensaver" downloads.

Nothing appears to happen. The executable runs, checks if it has admin rights (it does), and copies itself to %APPDATA%\Microsoft\Windows\ . It adds a registry key in HKCU\Software\Microsoft\Windows\CurrentVersion\Run to survive reboots. On XP, this is a one-way door.
