SIDCHG screenshotSIDCHG is a command-line urility which enables you to personalize local PC SID and PC name. It replaces the actual PC SID with new random SID. Additionally it customizes the WSUS ID for Windows Updates, the Microsoft Windows 8+ Device Identifier for Metro applications, and the encryption state to maintain encrypted files, Windows Action Center settings, Certificates and other encrypted saved information.

- /F: Omit confirmation
- /S: Shutdown when SID change is completed
- /WS: Set the number of seconds to wait reboot or shut down
- /FS: Force Shutdown or Reboot without terminating applications
- /KEY: License key
- /NS: Don't change SID, only set computer name
- /SK: Save licence key in registry for later. SID will not be customized if /SK is specified
- /RMK: Eliminate license key from registry after SID change
Following options are advanced (not for normal use):
- /CNMF: Map file and COMPNAME will be mapped against, with lines map=compname
- /OS: Windows-directory (e.g C:Windows) of OS to adjust, if not running OS
- /SID: New SID value. Per default, SID will be set to random value
