Explain what the Sysprep tool does in the Windows Server operating system and what it is used for.

Sysprep (System Preparation Tool) is a tool in Windows Server used to prepare the operating system for cloning and deployment on other machines.

Main functions of Sysprep:

• Removing unique system identifiers (SID) to avoid conflicts in the domain.
• Resetting Windows activation settings.
• Preparing the system for first boot (OOBE — Out-Of-Box Experience) so that the user can set up the system again.

Sysprep is used in mass deployment of servers or workstations with the same base configuration to avoid issues with uniqueness and to ensure proper setup on new machines.
