Unable to enable "Memory Integrity" on Win11 Solved

Question

Hello, I had opened a post on this subject and thought that a recent Windows update had fixed the issue, but I was mistaken: the problem reappeared very quickly. Since I can't remove the "Resolved" status from the previous post, I am creating this new one, and I apologize. I am on Win11 22H2 and I cannot enable "Memory Integrity" in windows defender. One of my drivers is incompatible with this activation. The problem is that I can't find the driver name to delete/disable it. Here is the driver in question  I can't find more information about this driver. I would indeed like to remove it via "cmd/powershell" I relied on this tutorial for help: https://allthings.how/how-to-fix-incompatible-drivers-error-for-memory-integrity-in-windows-11/ @billmaxime had responded to my previous post stating that it was the driver for Bluetooth/Bluetooth Adapter The problem is that I can't find it listed when I run the command "pnputil /enum-drivers" in powershell as suggested in "method 3" of the aforementioned tutorial If it helps, here is a screenshot of my device manager:   thank you for the help

Hello,  It's still surprising to have so many Bluetooth devices, making identification difficult.  CSR.plc most often corresponds to a chip manufacturer for USB Bluetooth dongles.  The question is not to remove it before knowing if it serves any purpose.  We can probably get some insights by editing (opening with Notepad) the corresponding oem inf file; the file in question does not directly launch the driver, but helps install it with the sys name that appears.  We can therefore start in services.msc to look for the service that launches the corresponding driver, set it to stopped and manual or disabled rather than automatic, and see if any Bluetooth device would stop working under these conditions before trying to uninstall the driver in question and the software that is probably associated with it.

Hello, The following PowerShell script lists the drivers:  $hostname = $ENV:COMPUTERNAME # Get Third Party drivers used, that are not provided by Microsoft and presumably included in the OS $drivers = Get-WmiObject Win32_PNPSignedDriver | where {$_.DriverProviderName -ne "Microsoft"} # Initialize the list of detected driver packages as an array $DriverFolders = @() foreach ($d in $drivers) { # We initialize the list of driver files for each driver $DriverFiles = @() # For each driver instance from WMI class Win32_PNPSignedDriver, we compose the related WMI object name from the other WMI driver class, Win32_PNPSignedDriverCIMDataFile $ModifiedDeviceID = $d.DeviceID -replace "\", "\" $Antecedent = "\" + $hostname + "\ROOT\cimv2:Win32_PNPSignedDriver.DeviceID=""$ModifiedDeviceID"""; # Get all related driver files for each driver listed in WMI class Win32_PNPSignedDriver $DriverFiles += Get-WmiObject Win32_PNPSignedDriverCIMDataFile | where {$_.Antecedent -eq $Antecedent} $DriverName = $d.DeviceName $DriverID = $d.DeviceID Write-Host "####Driver files for driver with name: $DriverName" -ForegroundColor Green Write-Host "and with DriverID: $DriverID" -ForegroundColor Green foreach ($i in $DriverFiles) { # We eliminate double backslashes from the file paths; $path = $i.Dependent.Split("=")[1] -replace '\\', '\' $path2 = $path.Substring(1,$path.Length-2) $InfItem = Get-Item -Path $path2 $Version = $InfItem.VersionInfo.FileVersion Write-Output "File: $path2" Write-Output "Version: $Version" } }  Best regards

Thank you for your help @brucine I opened services.msc but I can't find "csrbcx64.sys"   @hypothetix I ran the script, which gives me a long list of responses. I copied the response into a Word file so I could do a ctrl-F. I didn't find " csrbcx64.sys " but I found this: "05F988593351}_VID&0002054C_PID&0CD3\8&147A401A&0&38184C59E89D_C00000000 ####Driver files for driver with name: CSR GAIA™" Could this help?

Hello, Just a quick addition to brucine's post. To speed things up, we can use the command-line version autorunsc for example in administrator mode: autorunsc64.exe -a s -c >> services.csv https://learn.microsoft.com/en-us/sysinternals/downloads/autoruns

Hi You still have the same device alert in "Other Devices"   I think it's the one causing the problem Talk to you later

Matccm06 · Answer

Thank you for the help @brucine and @hypothetix I used Autoruns, disabled the file in question, restarted, but the problem persists:   @billmaxime, here is a screenshot of the device manager. We can clearly see a "CSR". Well done. The reading of these "devices" means absolutely nothing to me. Should I delete them?

billmaxime · Answer

hi I don't know what you have plugged into the PC?   @+

Matccm06 · Answer

@brucine Thank you Can’t I just delete these drivers? And what if I delete all my Bluetooth devices in the Bluetooth pairing settings?

Matccm06 · Answer

@brucine To remove the drivers, I assume I go through the device manager by right-clicking => uninstall but do I need to do another operation to delete the sys and oem.inf files? This might allow me to possibly bypass the Windows Defender update and, with a bit of luck, I no longer have the Bluetooth device that caused the problem :)

Matccm06 · Answer

Well, thank you I think I’m going to give up. Through "Settings-Devices-Bluetooth Devices," I deleted some Bluetooth devices, but they reappeared every time I restarted. So I removed, via the "Bluetooth Device Manager," those I no longer use. It didn't change anything. I don't feel capable of "directly deleting the concerned sys files via Autoruns or their location typically at C:\Windows\System32\drivers, but you need to know the name of the driver and/or its manufacturer." In fact, my main problem is that I don't have the exact name of the problematic driver. On other forums, some people have had the same issue but were able to identify the driver as shown in the following image:   I don’t have the details:   :/ Indeed, once the driver is identified, the method is as follows: t.ly/H8Nz (for some reason that I don't understand, I can't make my link clickable: t.ly/H8Nz)

Thank you Following the reading of this forum (t.ly/_Ga4), where the same problem is exposed, I suppose it is "'a device directly related to the installed hardware" but I am not certain of that What do you advise me to do? How risky is it to leave the computer like this ("memory integrity disabled)?

Matccm06 · Answer

Well, I'm going to leave it like that then and wait for an update to fix the issue... Thank you very much for your time and the explanations. I hope this post will be helpful to others.

Hello Did you connect a headset (via Bluetooth) to the PC? The printer, if it has Wi-Fi, can also cause this kind of issue (for peripherals with errors) For SMS/MMS, it's the phone See you

Matccm06 · Answer

@billmaxime thank you I just removed all my Bluetooth devices (including my headset) via the Bluetooth control panel and... still the same problem

billmaxime · Answer

hi and... still the same problem this one ==> Can't activate "memory integrity"? in the device manager, you no longer have a "Other devices" section and you no longer have any devices with alerts, the issue lies elsewhere for activating memory integrity see you

Matccm06 · Answer

Hello, Yes, the problem remains: "this one ==> Unable to activate 'memory integrity'?"             and you no longer have any devices alerting, the issue comes from elsewhere for memory integrity activation Yes, indeed... and I have no idea where from...

hi in the device manager, click on View ==> Show hidden devices, and post a screenshot I see you have a lot of Bluetooth hardware in the DM (Sony headset/soundbar/phone)   in search, type msinfo32 and click open give the info that I have highlighted (click on the image)   @+

Hi

Do you no longer have the incompatible driver message when you want to enable memory integrity?

Do this:

Plug the PC into the power outlet

Close all your running programs

In the search bar, type CMD and click on ==> Run as administrator

In the command prompt, type or copy/paste this CMD ==> Dism /Online /Cleanup-Image /RestoreHealth and hit Enter

At the end of the scan, you will see a message saying "the operation was successful"

Then, type this command ==> SFC /SCANNOW and hit Enter

WARNING: there is 1 space between SFC and /

At the end of the scan, check if it found/did not find/fixed any system files

Hello and thank you I still have the incompatible driver message when I want to enable memory integrity. I have followed the requested steps and I still get the message:

Matccm06 · Answer

Well done @billmaxime I successfully renamed the file to .old and activated kernel protection without any issues. Do you now recommend leaving my file as .old or changing it back to .sys?

billmaxime · Answer

hi Do you now advise me to leave my file as .old or to change it back to .sys? If you rename it to .Sys, you will get the incompatible driver error message. Have you checked if you have any issues with the Bluetooth connected devices? There is no driver beyond W8.1 for the device ==> click here   @+

Matccm06 · Answer

Hello

I don't have all my Bluetooth devices with me because I'm traveling, but the main ones are working perfectly.

Thank you

However, I don't understand what you mean by:

there is no driver beyond W8.1 for the device ==> click here

?

Do I need to install a new driver according to you?

billmaxime · Answer

Hi I don't have all my Bluetooth devices with me because I'm traveling, but the main ones are working perfectly. You will check that all your Bluetooth devices are working when you're back home. As for the driver, I meant to say that there isn't one for W10, and you don't need to install a new driver. See you later

Matccm06 · Answer

Well, thank you a thousand times then :D

billmaxime · Answer

hi no worries for the help :) PS: I'm waiting for you to test all your Bluetooth devices before I delete your topic from my followed discussions, or is everything okay for you? see you+

Matccm06 · Answer

If you can wait, that's nice, but... I won't be home for a few weeks or even a few months :) Thank you

hi since you don't know when you'll be home, send me a DM if you need anything once you're back here's the procedure ==> click here  let me know if that works for you @+
