A partição do Windows não está mais visível no Ubuntu

Question

Eu dual boot Ubuntu 16.04 e Windows 10. Era conveniente apenas clicar na partição do Windows no iniciador do desktop Ubuntu. Essa função desapareceu gradualmente e agora nada acontece quando clico nela. Meu Windows está desligado, não hibernado.

Eu poderia começar a fazer experimentos com fstab. Mas eu acho que o resultado é melhor se alguém aqui me orientar como recuperar essa função legal, apenas para clicar no ícone no lançador.

(Esta questão não é sobre GRUB e boot-loaders. Eles funcionam bem e tanto o Ubuntu quanto o Windows começam como eu escolho. Trata-se do desktop Ubuntu, onde não consigo mais acessar a partição do Windows com um clique do Ubuntu lançador.)

Desculpe por muitas edições, tenho lutado com tags de código nas listagens.
