OS4World then takes that update pack and embeds it into a clean, bootable ISO.
The most critical technical hurdle for installing vanilla Windows 7 on modern hardware is the lack of native USB 3.0/3.1 support. Modern motherboards utilize xHCI controllers that the original Windows 7 kernel did not support. The Adguard integration typically includes a generic driver pack, allowing the installation media to recognize keyboards and mice during the setup phase on modern Intel and AMD chipsets.

The Windows 7 SP1 x64 12 in 1 by Adguard August Updated OS4World 64 bit is a masterpiece of the abandonware and enthusiast community. It solves the real problem of installing a decade-old OS on modern-ish hardware by pre-injecting drivers, updates, and runtimes.

From a technical security standpoint: Cautiously usable, but not for banking.
The Adguard pack is well-respected in the collector community (MD5 hashes often posted on MyDigitalLife forums). However, OS4World is a repacker. The risk is that a third party added a backdoor to the $OEM$ folder.

The “12-in-1” designation refers to the twelve included editions of Windows 7, all within a single install.esd (highly compressed) for a manageable ISO size.
When you boot the installer, you will be presented with a list of editions. Since this is a "12-in-1" release, you will typically see variations of these four core versions:
The "12-in-1" count usually comes from having both x64 (64-bit) and x86 (32-bit) versions included, though your title specifies x64. It may also include "N" editions (versions created for the European market that exclude Windows Media Player).
