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.
The driver may not support isolation, or the isolation setting is incorrectly configured. printisolationhost exe
Navigate to:
HKLM\SYSTEM\CurrentControlSet\Control\Print Create DWORD: EnableIsolatedDrivers = 0 But this is a troubleshooting step only, not a permanent configuration. Modern Windows versions ignore this setting if drivers explicitly request isolation. printisolationhost
If you are determined to disable isolation globally (not recommended), you can set the following registry key: printisolationhost exe
