Windows 10: *RESOLVED* I am trying to resolve incompatible drivers for the core isolation but when I...

See reply below for how I solved my own issue.After updating to Windows 11 I noticed in the security section that I could turn on core isolation. I ran that but it came back with an error saying there are some drivers that are incompatible that I have to deal with before activating the core isolation. The three drivers in question are old, originally from 2007 I believe, and are tied to an old webcam that I used years ago but no longer use or have. The three in question are P0870Dev64.sys, P0870Evx64.sys, and P0870Usb64.sys all from Creative Technology Ltd.Anyway, I found the file location on

Unable to enable core isolation however no incompatible drivers listed

I have windows 11 and I am trying to enable windows core isolation. When I try to enable it says there are incompatible drivers. But when I click to review incompatible drivers none are listed. I am not sure what to do. I have tried restarting and scanning again but it's still preventing me from enabling with no incompatible drivers listed.

Thanks!

 

Core isolation can't be turned on but no incompatible drivers

Hello,

thank you for the reply. The registry editor suggestion actually worked - great! The core isolation option is now greyed out (the settings is managed by the administrator) but permanently on.

However, now the same problem is for the Hardware-enforced Stack Protection option below, which cannot be turned on "due to incompatible drivers", but there are no incompatible drivers found. Is there also a registry work-around?

Thank you

 

Core Isolation

What you have omitted to say is what exactly is the driver that is incompatible with Memory Integrity. To find out, try turning Memory Integrity on. Beneath your 'Scan again' button (and cut off in your screenshot) is a link that will tell you what the driver(s) are.....

There are two ways to resolve this: Either find a compatible version of the driver, or if it's not a driver you strictly need then uninstall it in Device Manager.
