Cortana is your assistant in Windows 10, offering many useful features that you can use with voice commands or typing in the search bar. However, not everyone is a fan of Cortana, and many users choose to disable it for a variety of reasons.
Disabled or not, Cortana shouldn’t consume an excessive amount of RAM, whether it’s running or not. However, some users have reported significant memory usage of Cortana. Users who have enabled Cortana have reported higher rates, while others have wondered how Cortana can use resources when it is disabled.
