Enable ‘Minimize on Click’ on Ubuntu Quickly
Just open a Terminal window and copy/paste the following command:
gsettings set org.gnome.shell.extensions.dash-to-dock click-action 'minimize'
Hit enter for the change to take effect instantly.
If you don’t want to lose the ‘window’ picker (option 5 in the list above) run this command instead, which will introduce minimise on click but show the window picker if more than one window of a given app is open:
gsettings set org.gnome.shell.extensions.dash-to-dock click-action 'minimize-or-previews'
To undo the change (i.e. revert back to the default settings for the Ubuntu Dock) copy/paste this command:
gsettings reset org.gnome.shell.extensions.dash-to-dock click-action
gsettings set org.gnome.shell.extensions.dash-to-dock click-action 'minimize'
Hit enter for the change to take effect instantly.

Gerenciar usuários por linha de comando no Windows
Para criar usuários locais com net user, digite:
1 net user nome_usuario senha /add
Substitua nome_usuario e senha pelos dados desejados. Você também pode ir além e
digitar o nome completo e a descrição do usuário com:
1 net user nome_usuario senha /add /fullname:"Nome Completo" /comment:"Descrição do usuário"
Caso queira alterar a senha de um usuário local, simplesmente digite:
1 net user nome_usuario nova_senha
Ou se quiser editar o nome completo ou a descrição, digite:
1 net user nome_usuario /fullname:"Novo nome Completo" /comment:"Nova descrição do usuário"
Utilizando este método, você vai criar usuários “Padrão”, ou seja, sem privilégios
administrativos. Para dar privilégios de administrador para determinado usuário,
simplesmente digite:
1 net localgroup administradores nome_usuario /add
Caso tenha pensado melhor e acha que o usuário não merece ser um administrador,
digite:
1 net localgroup administradores nome_usuario /delete
