SIDCHG64 [options]
  /COMPNAME=: New computername, ? = random hex character, * = mac address (hex)
  /COMPDESCR=: New computer description
  /F: Omit confirmation
  /R: Reboot after SID change
  /S: Shutdown after SID change

  /KEY=: License key
  /SK: Store licence key in registry for later. SID will not be changed if /SK is specified
  /RMK: Remove license key from registry after SID change
  /OD: Reset OneDrive. This avoids OneDrive synchronization issues if both original and clone are active with same user. /OD requires OneDrive-Account to be reentered after SID change. Without /OD it is sufficient to reenter password of OneDrive-Account after SID change
  /RESETALLAPPS: Reset all Modern Apps. This avoids issues with Modern Apps or with Search box after SID change.
  /RESETAPPS=: List of Modern Apps to be reset (PackageFamilyName), separated by ;-character. *-character counts as wildcard. - (minus)-character at beginning excludes app from reset.
  /RESETAPPSFILE=: File containing List of Modern Apps to be reset (PackageFamilyName), each on separate line. *-character counts as wildcard. - (minus)-character at beginning excludes app from reset.
 Following options are advanced (not for normal use):
  /OS=: Windows-directory (e.g /OS=D:\Windows) of OS to modify, if not running OS
  /D=: Drives to check for SID (e.g /D=CDE). Per default, SID will be changed on all local harddrives
  /SID=: New SID value. Per default, SID will be set to random value
  /RMKNOW: Remove stored license key from registry without doing SID change
  /RMT: Remove traces. Remove SIDCHG key from registry after SID change. Completed SID change cannot be reverted if /RMT is specified
  /RMTNOW: Remove traces now. Remove SIDCHG key from registry without doing SID change. SID change cannot be reverted afterwards
  /NW: Don't change WSUS ID
  /NCID: Don't reset MSDTC CID
  /NPP: No Run Once-post processing. Transparent post processing is needed to preserve encrypted files and other user settings.

  /NMID: Don't reset Machine ID

  /FDID: Full reset of Device ID (can invalidate System Activation)
  /REVERT: Reverts SID back to previous value after complete or interrupted SID change
  /REPEAT: Repeats previous complete or interrupted SID change with same previous and new SID values. This can be useful if not all has been changed during first run.
  /CLEARMSG: Clears SID change message at login after interrupted SID change
  /CNMF=: Map file /COMPNAME will be mapped against, with lines map=compname
  /FF: Allow SID change with Antivirus real-time protection left on, SID to be changed on removable drive, or for unsupported Windows version, and bypass other restrictions.
Best usage examples:
 SIDCHG64
 SIDCHG64 /COMPNAME=compname
 SIDCHG64 /COMPNAME=compname /F /R /OD /RESETALLAPPS

Set computername after mac address:
 SIDCHG /COMPNAME=* /CNMF=map.txt      where map.txt has lines macaddress=compname

Change of computer SID risks data loss and system damage. Do not interrupt SID change in process!
