How to "permanently" disable Powershell IntelliSense

2023-12-15

Powershell Intellisense is where Powershell tries to guess what you're going to type based on your command history. It's not aware of any current context, so the predictions are generally bad for non-system-administrators.

To turn it off "permanently":

• Start Powershell
• From the prompt, run:
  • $profile
• Edit the file that's displayed or create it if it doesn't exist
• Add the following line:
  • Set-PSReadlineOption -PredictionSource None
• Save the file and restart Powershell

To enable IntelliSense again, delete the added line.
