Printisolationhost Exe Extra Quality

printisolationhost.exe is a protected system file. Even if you delete it (which requires taking ownership and overriding permissions), Windows File Protection will restore it. Moreover, disabling print isolation would revert to the dangerous pre-Windows 7 model where drivers run inside the spooler.
