You need to run sysprep with the generalize option.
Resetting Windows Activation
When you install Windows with a single license product key, you have 30
days during which you must activate that installation of Windows. If you do
not activate Windows within the 30 day period and do not reset the
activation clock, Windows will enter RFM (Reduced Functionality Mode). This
mode prevents users from logging on to the computer until Windows is

There is no limit to the number of times Sysprep can run on a computer.

time you run the sysprep /generalize command, the clock can no longer be
When you run the sysprep /generalize command, the activation clock will
automatically reset. You can bypass resetting the activation clock by using
the SkipRearm setting in the Microsoft-Windows-Security-Licensing-SLC
component. This enables you to run Sysprep multiple times without resetting
the activation clock. For more information about this setting, see the
Unattended Windows Setup Reference.
