Making HVConfig work on a normal Server Core installation

Reading Time: 2 minutes

Microsoft's Hyper-V Server 2008 product comes with a wizard, that allows easy configuration of the Server Core-based subsystem.

This tool can be used on normal Server Core installations of Windows Server 2008 too. This blogpost describes what files to copy from a US English Hyper-V Server 2008 installation, where to place them and how to install this wizard to autorun. All in five easy steps! šŸ™‚

When you're using a different language change the En-Us bit for the files accordingly:

Language String
US English en-US
Spanish es-ES
German de-DE
French fr-FR
Italian it-IT
Japanese ja-JP
Korean ko-KR
Portugese (Brazil) pt-BR
Russian ru-RU
Simplified Chinese zh-CN
Chinese (Hong Kong) zh-TW
Chinese (Taiwan) zh-TW


Step 1

You will need to following files from a Hyper-V Server 2008 installation:

  • C:\Windows\System32\hvconfig.cmd
  • C:\Windows\System32\en-US\hvconfig.vbs
  • C:\Windows\System32\en-US\WUA_SearchDownloadInstall.vbs


Step 2

Copy the files to their respective location on your Server Core installation.
Review the instruction here to get files onto your Server Core box.


Step 3

Open the Registry Editor, by running regedit.exe and browse to the following location:


Create a new String value (REG_SZ) named HVConfig. Right click it and select Modify Data from the context menu. Type C:\Windows\system32\hvconfig.cmd as the data and press the OK button to save.

Close the Registry Editor.


Step 4

Log off by typing logoff on the command prompt. Log on using an account with administrative privileges.


Step 5 (Optional)

Optionally change the contents of hvconfig.vbs to display another header.
Since we're no longer running the script on Hyper-V Server it would be appropriate to change the top banner.

Type the following command:

Notepad.exe C:\Windows\system32\en-US\hvconfig.vbs

Now change the L_Msg005_Text constant to something appropriate.

You can also change the color of the screen by changing the second line in HVConfig.cmd. Default color is 17 (White on Blue), but I prefer 47. (White on Red)



CoreConfigurator and CoreConfig are great tools, but HVConfig can be used just the same…
