These are the builds of Windows (Codename) 7 that the WinLibrary team has been able to obtain. They should each contain the BIOS date required for the system to boot (timebomb) and (if applicable) the product key required for installation. Some builds might not have both a 32-bit and a 64-bit version available for download, but we are trying to obtain all builds in both architectures. Please contact us at contact@winlibrary.net if you have more versions. Enjoy!
