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.
If you plan to install this:
Alternative recommendation: Use the official Microsoft "Update Readiness Tool" to create your own slipstreamed ISO. It takes 2 hours, but you control the source. If you decide to use the Windows 7
This is a custom, pre-tweaked, and fully updated Windows 7 SP1 x64 ISO compilation, assembled by Adguard (known for their activation tools and clean repacks) and distributed via OS4World. Labeled as the August Updated release, it integrates all critical, security, and optional updates up until August of its release year, saving hours of Windows Update time after installation.
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.
OS4World acts as a repository for "pre-activated" or "pre-configured" operating systems. In the context of this 12-in-1 release, OS4World may have added: This is a custom, pre-tweaked, and fully updated

What makes this version special? The "by Adguard" tag implies that the image is slipstreamed. This means the creator used tools (like NTLite or MSMG Toolkit) to physically embed updates into the install.wim file.
Without slipstreaming, installing Windows 7 SP1 from a vanilla ISO takes 3+ hours just to download updates from Windows Update (which is now officially dead for Windows 7). This custom image reduces post-install update time to zero.
The term "Adguard" in this context refers not to the ad-blocking software, but to a suite of tools (often developed by community figures like "Adguard" or utilizing the "AG" script methodologies) used for integration.
Standard Windows 7 SP1 media is outdated. Installing it on a modern PC requires manual injection of USB 3.0 drivers and NVMe storage drivers, or the installation process will fail (keyboard/mouse won't work, or the drive won't be detected). The "Adguard" methodology involves using the Microsoft DISM (Deployment Image Servicing and Management) tool to inject these drivers and the cumulative updates directly into the install.wim file before installation. This is often referred to as "Slipstreaming."
