Because these ISOs were distributed on unregulated file-sharing sites, there was zero supply chain security. Users had to entirely trust an anonymous modder. It was incredibly easy for a creator—or a malicious third party modifying the torrent—to slip keyloggers, remote access trojans (RATs), or rootkits deep into the system files. 2. Broken Windows Update
Modders often disabled unnecessary services, startup programs, and visual effects to make the OS feel faster and lighter, particularly on older hardware.

In 2013, many users were still running older hardware with limited RAM and mechanical hard drives. To make Windows 8 run faster, the creators aggressively gutted the operating system. Modders typically removed:

During the early 2010s, modified versions of Windows—often called "unattended" or "lite" editions—flooded file-sharing networks. These projects aimed to fix the perceived flaws of official releases.
