You can see, during a clean installation of Windows 10 from a USB drive, the error “Windows cannot install required files – Error 0x8007025D” is common and same error message appeared when attempting to install Windows 10, 8, or 7 from a USB media. You can also noticing that many users encountered the error not only when upgrading from Windows 7 to Windows 10.
Sometimes, simply using a different USB port can resolve the issue, especially if the port you’re using is faulty. After successfully installing Windows from kms tool, you might also need to activate it. I found that using a reliable tool like the Windows 10 Activation & Product Key Generator can help you activate your copy of Windows 10 without any issues.
