Get Windows 7 SP1-U Media Refresh MSDN/TechNet ISO
Complete article at:
Microsoft has published a new refresh version of Windows 7 with SP1 integrated ISO media on May 12, 2011, which fixes a minor issue which causes Windows 7 SP1 media cannot be used to install on new PC. The Windows 7 SP1-U (Media Refresh version) includes the installation hotfix KB2534111, and nothing else. No other changes have been made to the Windows 7 with SP1 ISO image despite there are tens of updates been released after the Windows 7 SP1 was released.
KB2534111 is a hotfix which fixes “Computer name cannot contain only numbers, may not be identical with the user name and cannot contain spaces. Retype the name of the computer” error when installing Windows 7 by using Windows 7 SP1 integrated installation media. The error happens when user sets the Time and Currency Format setting to a locale other than English, Finnish, German, and Swedish during initial installation, or the locale was selected before the computer is purchased, and then a computer name that contains non-ASCII characters is entered in the Out of Box Experience (OOBE) Wizard.
The error is not considered to be show-stopping though, as end-users can always manually remove any non-ASCII characters from the computer name so that the installation can proceed, and revert the computer name to original preferred name that contains non-ASCII characters after the installation process is complete.
Nonetheless, Microsoft is still updating all distributions and languages of the Windows 7 with SP1 slipstreamed media to include the hotfix, where the new ISO images downloaded from MSDN or TechNet Subscriber Downloads include a “u” in the file name, or known as Windows 7 SP1-U to indicate the media refresh version. Interestingly, Windows Server 2008 R2 with SP1 integrated media is not affected by the issue, and thus has not been updated.
