Customers who try to install Windows 7 by starting the computer from integrated installation media with Service Pack 1. "During the initial installation, you set the Time and Currency Format setting to a locale other than English, Finnish, German, or Swedish. Or, the locale was selected for you before you purchased your computer. A computer name that contains non-ASCII characters is entered in the Out of Box Experience (OOBE) Wizard," explained Microsoft in KB2534111.

In this scenario, you receive an error message that resembles the following:

"Computer name cannot contain only numbers, may not be identical with the user name and cannot contain spaces. Retype the name of the computer."

To fix the issue, the company provided a hotfix package for OEMs and enterprises that build Windows 7 installation images. If you are a user who experiences this issue, read the methods below:

  1. Manually delete any non-ASCII characters from the computer name. This includes strings that are generated automatically. To manually delete non-ASCII characters from the computer name, you may have to switch to an English keyboard setting. The English keyboard setting is available for all language settings and locales. You can revert the computer name to a name that contains non-ASCII characters after the installation process is complete.
  2. Restart the OOBE Wizard by using audit mode and Sysprep. You can enter audit mode by pressing CTRL+Shift+F3 at the computer name screen in the OOBE Wizard. After the computer restarts, start the OOBE Wizard by running the SYSPREP /OOBE command.
  3. Build the Windows installation image by using the Sysprep tool. There are legal requirements for OEM system builders regarding the installation of Windows 7.
  4. Force the OOBE Wizard to display the Country/Region/Keyboard settings page by changing the OOBE.xml file. To do this, set the hideRegionalSettings registry subkey to false.
