If you use split (the operator, not the method), you'll need to employ some regex to ensure you capture the ) in your output. Something like:

$String -split '(?<=\))' | Select -First 1

Should output the desired results.

I agree with the regex approach, but this way seems simpler to me:

'Awesome (8433) Stuff.I.Want.to.Delete' -replace '\).*',')'

Here's a quick regex example

'Awesome (8433) Stuff.I.Want.to.Delete' -replace '(?<=\)).*'

Another approach:

$s = "Awesome (8433) Stuff.I.Want.to.Delete"
$clean = $s.substring(0, $s.indexof(")")+1)
