Re: When do i need [void]?

Tech-Archive recommends: Fix windows errors by optimizing your registry

You can always rely upon a SCOPE to make this work a little easier:

MSH> &{$erroractionPreference = "silentlycontinue"; spps 43};spps 23
stop-process : No process with process ID 23 was found.
At line:1 char:61
+ &{$erroractionPreference = "silentlycontinue"; spps 43};spps <<<< 23
MSH>


&{} runs a the enclosed code in a new SCOPE.
Setting $ErrorActionPreference in the new scope creates a COPY of the
variable to be used in that scope. This is why the "spps 43" does not
generate an error message.
Exiting the scope tosses the variable so you get the original value which is
why spps 23 generates an error.
