  • ONLY FOR SLMGR – Always make sure that when you type any command starting with SLMGR for example SLMGR -REARM there is a single space between the dash (-) and SLMGR so always keep a check on this while executing any SLMGR command.

Common Reasons for such error:

  • You are not running command prompt with administrative privileges.
  • The command you have typed is not in right format i.e. command should be like SLMGR -REARM and not like SLMGR-REARM here check the space between the commands.
  • ONLY FOR SLMGR – You have reached the maximum threshold of using the SLMGR command i.e. SLMGR -REARM command that provides only limited attempts.
