Default Location for Sysprep Files on VMware vCenter Server 5.0


If vCenter Server is installed on Windows Server 2008 and above, <directory_path> is %ALLUSERSPROFILE%\VMware\VMware VirtualCenter\Sysprepwhich generally translates to C:\ProgramData\VMware\VMware VirtualCenter\Sysprep by default.

Note: C:\ProgramData may be a hidden folder.
If vCenter Server is installed on any other Windows operating system, <directory_path> is %ALLUSERSPROFILE%\Application Data\VMware\VMware VirtualCenter\Sysprep\ which generally translates to C:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter\Sysprep\ by default.

if vCenter is appliance then /etc/vmware-vpx/sysprep/

Under above mentioned location as per the vCenter version you have there are folder for Operationg Systems
like for Server 2003 32 bit there is folder svr2003. you need to copy the sysprep files after this while you deploy the VM using template or clone, wizard will offer you the choice to customize the OS...
