To clear a variable's content in PowerShell, you can simply assign it a value of $null or an empty string.

Here is an example:

$variable = "This is some content"
$variable = $null

Alternatively, you can also use the Set-Variable cmdlet to clear a variable's content:

Set-Variable -Name variable -Value $null
