How to activate Windows

  1. Connect to the university fixed network (ethernet).
  2. First start a command window as administrator.
  3. The command slmgr.vbs /ato should try to do an automatic activation if the computer is part of the Active Directory. If it is not part if the Active Directory you need to specify the KMS-server, see below.
