Windows 8.x setup files for Windows 7 AIO (install.esd) As you obviously already know, Windows 7 setup files are not able to read esd files and the common solution turns out to be the use of Windows 8.x setup files. I see 2 main advantages doing that: 1. Possibility to make use of esd files. 2. Workaround the lack of mass storage drivers found in Windows 7 boot.wim sufficiently compatible with newer controllers. However, I need to know: a. Potential disadvantages, issues, loss of functionality, if any, and else advantages I can't see or think right now. b. Is it correct to use the whole setup files found on Windows 8.x installation media?
