Windows 11 25H2 cannot load Driver HpPortlox64.sys with Core Isolation and Memory Integrity enabled.  I am looking for a replacement for this driver.

Greetings @jhmagill1 

 

I'm seeing two possible causes for this error in this Forum.

 

1. An older HP printer driver. Update your HP: printer software and drivers if applicable.

 

2. An older version of HP Omen Gaming Hub.

 

No Forum solutions were associated with either cause. I can't say if updating HP software will fix the problem.

Greetings @Houssss 

 

Windows Security is flagging the HP system driver (printing and scanning).

 

HP would have to provide a newer driver which works with Windows Security or you would have to turn off (not recommended): Memory Integrity.

 

Check your HP printer's download site for the latest downloads.

 

Uninstall the current printer software. 

 

Install the latest printer software.
