Every time I restart my computer I get a Creative Cloud message: "5 fonts were activated"

Hi Rachel,

Sorry for the delay in response. I would suggest checking this thread: https://community.adobe.com/t5/adobe-fonts/how-to-turn-off-automatic-font-activation/m-p/11355960 that looks similar to what you are requesting. However, if you are using any specific Adobe Application on which there is a file with a new text then Creative Cloud automatically searches for that font at Adobe Fonts and if there is a similar font available then it will activate those fonts.

Let me know if you need more assistance.

Thanks,

Harshika
