How to disable all aliases in PowerShell

Hello,

I want to disable the use of aliases (to avoid typing incorrect command abbreviations) in PowerShell 7.6.3.

To do this, first:

For $PROFILE + Temporary Session

I tried some commands that delete all aliases, writing them in the $PROFILE section.

For testing, I used abbreviated alias -> Some utils reactivated the module with import module and brought the alias back. And a few others did the same thing.

I have confirmed with Copilot AI that this cannot be done directly.

Is there anyone who can explain to me step-by-step how to solve this?

Sincerely,

MovelessMove.

Hi MovelessMove-0585,

This is a core PowerShell architectural behavior, and your prior assessment is completely correct. There is no native configuration or environment variable that globally and permanently disables alias resolution in PowerShell 7.6.3. When you delete items from the Alias:\ drive within your $PROFILE script, you only clear the aliases present in the initial state of that specific runspace. As soon as you execute a utility requiring a module, PowerShell automatically initiates an import process. The engine reads the module's .psd1 manifest file and pulls all variables listed under the AliasesToExport key straight back into your active session.

Attempting to continuously force the deletion of these aliases during module loading would severely degrade console performance and inevitably break built-in utilities that depend on those exact abbreviations for their background tasks. The industry standard solution is to shift this strict enforcement from the console runtime into your authoring environment. By utilizing the official PowerShell PSScriptAnalyzer module within a script editor like Visual Studio Code, the environment evaluates your code against strict rules such as PSAvoidUsingCmdletAliases. It will immediately flag any typed alias and automatically suggest the fully qualified command name. This approach corrects your scripting habits in real-time while leaving the fundamental, required PowerShell architecture intact and fully supported.
