How to Troubleshoot Cortana Using Memory on Windows 10 Computer

Cortana is a Windows 10 assistant that offers several useful features that you can use via voice commands or by typing them into the search bar. However, not everyone likes using Cortana, and many users disable Cortana for a variety of reasons. One such reason is Cortana’s high memory consumption.

Users who enabled Cortana reported higher rates, while other users wondered how Cortana could use resources if it is disabled. Users have found ways to solve this problem, and you should check them out below to learn more about the problem.

Why is Cortana consuming high memory?
