Quite often I make system images of Windows OS using Sysprep. The latest delivery of Dell laptops with preinstalled Windows happily greeted me the message “A fatal error occurred while trying to sysprep the machine.” The same problem occurred after installing OS from a DVD, without Dell utilities. I began to suspect that it is a matter of the operating system.
[ENG]: “A fatal error occurred while trying to sysprep the machine.”
[PL]: “Wystąpił błąd krytyczny podczas próby wykonania programu sysprep na komputerze”
The problem is: WMPNetworkSvc (Windows 7 Media Player Network Sharing Service)
Solution:
Before Sysprep stop wmpnetworksvc service by command-line or in services.msc
In my case the service wmpnetworksvc was disabled but Sysprep generate a fatal error.
The solution was to start, and then stop wmpnetworksvc services.
This solution helped me to make image of Win7 OS by Sysprep tool.
