1. Create a PowerShell profile if you have not.
	`New-Item $profile -force -itemtype file`
2. Edit the profile.
	`notepad $profile`
3. Add the aliases you wish to remove.
	`remove-item alias:<command>`
4. Save and close the PowerShell to reload the profile, or if you wish to use the same window issue the command `. $profile` to reload the profile.
5. This can be stepped if you run PowerShell

If you wish to run PowerShell with the defaults you can run it using the `-NoProfile` flag on the Run window or simply delete the profile that was created.
