Hello,
You can modify default behavior of all cmdlets by editing the “PSDefaultParameterValues” variable :
$PSDefaultParameterValues | Get-Member
You can edit it like that :
$PSDefaultParameterValues["Write-Host:ForeGroundColor"] = "Green"
Before :
After :
You can see all past modification like this :
$PSDefaultParameterValues
And delete them :
$PSDefaultParameterValues.Clear()
I just put some of those in my profile, pretty handy !
