Push-button reset features in WinRE don't work when an image is duplicated in Windows 8.1

S'aplica a: Windows 8.1Windows 8.1 EnterpriseWindows 8.1 Pro


Consider the following scenario:
  • You have two hard disks that are different sizes.
  • You install Windows 8.1 on one of them, and then you create an image of it.
  • You duplicate the image to the other hard disk drive by using disk duplication software or disk imaging software.
In this scenario, the push-button reset features in the Windows Recovery Environment (WinRE) don't work on the new hard disk because the offset that's listed in the Reagent.xml file is incorrect.


To resolve this issue, apply the following hotfix to the computer that's running Windows 8.1. This hotfix must also be applied to your Windows Recovery images. To learn how to update Windows Recovery images, see the "More Information" section.

Information about how to update Windows Recovery images

Warning This section contains steps that should be performed only by a qualified technical person who is familiar with the Windows recovery mechanism. Serious problems might occur if you perform the steps incorrectly. Incorrect steps can leave the Windows recovery mechanism in an unrecoverable state. Therefore, make sure that you follow these steps carefully. For added protection, perform a complete system backup before you continue. Also, be aware that you may need the Windows installation media that was originally used to install the operating system.

For more information about the procedures and terminology that are used in this article, see the following Microsoft websites: The following procedures should be performed by an administrative user at an administrative command prompt. These procedures contain guidance only for a generic installation. This guidance may differ for your installation.

Locate and copy an installed version of WinRE.wim

If WinRE.wim is already configured on the system, follow these steps:
  1. Type the following command to find the location of the installed Windows RE image file (Winre.wim):

    reagentc /info

    • The WinRE.wim file may have the SYSTEM and HIDDEN file attributes set. Use the Attrib command to remove these attributes.
    • WinRE.wim may be in a hidden directory or a hidden partition. Use the DIR /A command to find hidden folders and files. If necessary, use the Diskpart utility to unhide the partition.
  2. Note the location of the WinRE.wim—for example, <WinREdrive>\WindowsRE\<GUIID>.
  3. Copy the currently installed WinRE.wim file to a local folder such as C:\WinRE. The local folder must differ from the installation location. Make sure that you keep a backup of C:\WinRE\WinRE.wim.

Locate and copy WinRE.wim from the installation media

If WinRE.wim is not configured on the system, follow these steps:
  1. Locate the WinRE.wim file on the Windows installation media that was used to install the operating system.
  2. Create the following local folders:
    • C:\OS_Image
    • C:\OS_Image\Mount
    • C:\Winre
  3. Copy the Install.wim file from Windows installation media to C:\OS_Image. If the installation media is on drive D, the Install.wim file will be located in the D:\sources folder.
  4. Type the following DISM command to mount the Install.wim file:

    DISM /mount-wim /wimfile:C:\OS_Image\Install.wim /index:1 /MountDir:C:\OS_Image\mount
  5. Type the following command to copy the Windows RE image (Winre.wim) file from the mounted Windows image to C:\WinRE:

    Copy C:\OS_image\mount\windows\system32\recovery\WinRE.wim C:\winre\
  6. Type the following command to unmount the mounted Windows image:

    DISM /unmount-wim /MountDir:C:\OS_Image\mount /discard
  7. Delete the C:\OS_Image and C:\OS_Image\Mount folders together with the Install.wim file that was copied to them.

Insert the KB2930296 hotfix package into WinRE.wim

  1. Copy the KB2930296 hotfix package to the C:\WindowsUpdate folder.
  2. Create the following local folder:
    • C:\WinRE\Mount
  3. Type the following command to mount the Winre.wim file:

    DISM /mount-wim /wimfile:C:\winre\WinRE.wim /index:1 /MountDir:C:\winre\mount
  4. Type the following command to insert the security package into the mounted Winre.wim file:

    DISM /image:C:\Winre\mount /Add-Package /Packagepath:C:\WindowsUpdate
  5. Type the following command to verify that the security package was integrated successfully:

    DISM /image:C:\winre\mount /Get-Packages
  6. Type the following command to commit the changes to the Winre.wim file:

    DISM /unmount-wim /MountDir:C:\Winre\mount /commit

Deploy or copy a modified WinRE.wim

If WinRE.wim is already installed and configured, follow these steps:
  1. Move C:\WinRE\WinRE.wim to the folder where WinRE.wim was located earlier. For example, you might have to move it to <WinREdrive>\WindowsRE\<GUIID>. Overwrite the existing WinRE.wim if you are prompted about this.
  2. Use the Attrib command to restore the SYSTEM and HIDDEN file attributes to the previous settings.
  3. If <WinREdrive> was previously hidden, use the Diskpart utility to hide the partition again.
  4. Deploy and configure the customized Windows RE image if it was not located on the installation media.
  5. The C:\WinRe and C:\WinRE\Mount folders can now be removed.

Validate and roll back if necessary

  1. Verify that you can start in the modified WINRE environment and that you can perform previously configured recovery functions.
  2. If validation fails, make sure that you revert the changes that were made. To do this, follow these steps:
    1. Unconfigure and delete the WinRE.wim file if it was copied from installation media.
    2. Replace the modified WinRE.wim with the backup copy if you modified an already configured WinRE.wim file.
