For daily use, modern hardware requires a fully supported, secure operating system like Windows 11 or a mainstream Linux distribution customized with a dark theme.
The custom operating system is a modified, unofficial release of Microsoft's classic OS distributed through communities like TeamOS and HKRG. To understand the relevance of this specific ISO,
The primary goal of this release was to provide an "out-of-the-box" dark aesthetic combined with system optimization, pre-installed software, and registry tweaks designed to make the operating system run faster on 2015-era hardware. Key Visual and System Features

Because Windows 7 is entirely deprecated, it does not receive modern security patches. Running a 2015 custom version means your system is entirely defenseless against exploits discovered over the last decade (such as EternalBlue or BlueKeep). 3. Missing System Files
