The Core isolation page in Windows Security may show that the Memory integrity feature is off and your device may be vulnerable. It suggests that you resolve any driver incompatibilities and try again. If you try to enable Memory integrity or click “Scan again”, the “Incompatible drivers” page may be empty.<\/p>\n

\"memory<\/p>\n

\"memory<\/p>\n

The above page is supposed to show the list of incompatible drivers and driver packages on the computer.\u00a0For more information, see\u00a0Cannot Enable Core Isolation Due to Incompatible Drivers<\/a>.<\/p>\n

The Memory integrity scan checks each driver for HVCI compatibility and list the incompatible drivers. If the list is empty, you wonder if there are any other ways to narrow down the driver\/driver package stopping you from enabling memory integrity.<\/p>\n

Resolution<\/h2>\n

Sometimes, the integrity scan doesn’t show the incompatible drivers. As an alternative to the built-in Memory integrity scanner, you can run the standalone scanner (hvciscan_amd64.exe<\/strong>) from Microsoft. This tool scans each driver to check if it complies with the Memory integrity feature.<\/p>\n

Please download the Memory Integrity readiness console tool from Microsoft:<\/p>\n

https:\/\/www.microsoft.com\/en-us\/download\/details.aspx?id=105437<\/a><\/p>\n

Copy the file “hvciscan_amd64.exe” to a folder on the C drive’s root–e.g., C:\\Tools\\<\/p>\n

Open an admin Command Prompt<\/a> and run:<\/p>\n

c:\\tools\\hvciscan_amd64.exe<\/pre>\n
And then run:<\/p>\n
c:\\tools\\hvciscan_amd64.exe KCET<\/pre>\n
The output of the first command shows a list of drivers incompatible with the Memory integrity. The second command lists drivers or services that don’t support the Control-flow Enforcement Technology feature.<\/p>\n
Here’s a sample output for the above two commands:<\/p>\n
VbsGetIssues: 0x00000000\r\nVbsIsRecommended: 1\r\nHVCI incompatible driver scan start...\r\nHVCI: Error 1168 querying \"driver\/INF file name\" in the SDB\r\nHVCI: Driver scanning complete\r\nHVCI: scan get result failed.\r\n\r\n\r\nKernel-mode CET incompatible driver scan start...\r\nKernel-mode CET: Error 1168 querying \"driver\/INF file name\" in the SDB\r\nKernel-mode CET: [driver\/service executable] is marked as incompatible with kernel-mode CET in the SDB\r\nKernel-mode CET: Driver scanning complete.\r\nKernel-mode CET: Scan get result failed.<\/pre>\n
\"memory<\/p>\n
Error 1168<\/strong> (hex: 0x80070490) translates to ERROR_NOT_FOUND or “Element not found.” The driver file may not exist on the system, but a reference to it may exist in the driver store.<\/p>\n
In the above example, the offending driver name is dddriver64dcsa.inf, which is related to Dell Data Vault Control Device<\/strong> (DDV Device). Dell provides instructions<\/a> on uninstalling the device (using Device Manager) along with the driver store package.\u00a0<\/em>If that doesn’t work or the device is not found, uninstall the drivers manually.<\/em><\/div>\n
Uninstall the incompatible driver(s)<\/h3>\n
To resolve the problem, completely uninstall the driver using PnpUtil<\/strong> (for driver store\/INF packages) or Autoruns<\/strong> (for drivers).\u00a0For more information, see How to Completely Uninstall a Driver<\/a>.<\/p>\n
Example:<\/h4>\n
Step 1: Get the list of driver packages<\/strong><\/p>\n
dism \/online \/get-drivers \/format:table<\/pre>\n
The DISM output showed the following:<\/p>\n
oem16.inf | dddriver64dcsa.inf | No | System | Dell Technologies | 7\/26\/2021 | 2.0.6.0<\/pre>\n
Step 2: Uninstall the driver package<\/strong><\/p>\n
Now that the OEM INF # is known, we can uninstall it using PnpUtil.exe.<\/p>\n
pnputil \/delete-driver oem16.inf \/uninstall \/force<\/pre>\n
Important:<\/strong> The INF # will vary<\/strong> from computer to computer. First, you need to find the OEM INF # using DISM. For more information, see How to Completely Uninstall a Driver<\/a>.<\/div>\n
Step 3: Delete the driver service<\/strong><\/p>\n
Open Command Prompt (admin) and run:<\/p>\n
\r\nsc.exe delete DDDriver\r\n<\/pre>\n
Restart Windows and then rename or delete the following driver file if it exists:<\/p>\n
\r\nC:\\WINDOWS\\System32\\drivers\\dddriver64Dcsa.sys\r\n<\/pre>\n
After successfully uninstalling the driver, you should be able to enable Memory Integrity.<\/p>\n
\n<\/hr>\n
Additional Information<\/h3>\n
If no incompatible drivers are found, the hvciscan_amd64.exe tool shows the following output:<\/p>\n
C:\\Windows\\System32>\"C:\\Tools\\hvciscan_amd64.exe\"\r\nVbsGetIssues: 0x00004080\r\nVbsIsRecommended: 0\r\nHVCI incompatible driver scan start...\r\nHVCI: Driver scanning complete\r\nHVCI incompatible driver scan passed!<\/strong>\r\n\r\nC:\\Windows\\System32>\"C:\\Tools\\hvciscan_amd64.exe\" kcet\r\nVbsGetIssues: 0x00004080\r\nVbsIsRecommended: 0\r\nKernel-mode CET incompatible driver scan start...\r\nKernel-mode CET: Driver scanning complete\r\nKernel-mode CET incompatible driver scan passed!<\/strong>\r\n<\/pre>\n
I hope the above information helps.<\/p>\n","protected":false},"excerpt":{"rendered":"
