After you download and install the Microsoft Sysprep tool from the Microsoft Web site, you can use the VMware vCenter Server Appliance Web console to upload the files to the appliance.


Verify that you download the correct version for the guest operating system to customize. Microsoft has a different version of Sysprep for each release and service pack of Windows. You must use the version of Sysprep specific to the operating system that you are deploying.

When you upload the files to vCenter Server Appliance, the contents of the CAB file for the Sysprep Tool version that you downloaded are saved in /etc/vmware-vpx/sysprep/OS. For example, /etc/vmware-vpx/sysprep/2k or /etc/vmware-vpx/sysprep/xp.


  1. Download the Sysprep files from the Microsoft Download Center and save them to your local system.
  2. Log in to the VMware vCenter Server Appliance Web console and click the vCenter Server Summary tab.
  3. In the Utilities panel, click the Sysprep Files Upload button.
  4. Select a Windows platform directory, and browse to the file.
  5. Click Open.
    The file is uploaded to the VCenter Server Appliance.
  6. Click Close.
