Hello,

hopefully i'm in the right category. i'm having problems with windows 11 core isolation/memory integrity. It does not turn on and when I review incompatible drivers. There is none listed. A few days back I had the same problem but this time there was one driver listed. The name of the driver  was “vacnatkd.sys” and published oem146.inf. It was a media driver according to the heading under the driver's name. Since it stated that it was an older driver(2016) I went ahead and deleted. Now, hindsight 2020, i'm thinking maybe that action is causing this new problem. So, can you, please, help me resolve this dilemma. My system is a dell inspiron 3910 desktop running windows 11 64bit and my antivirus is windows security.

 

Thank You in advance

Hi rigs,

 

Sounds like it would be best to check for any system file and/or driver corruption with the System File Checker (SFC).

 

Have you tried to reset the Windows Security app?

Hello, DKenn

 

Thank you for replyi to my message....

 

I did perform [both of your suggestions.

 

First I ran the sfc /scannow since that command scans and fixes any corrupted files. It scanned my HD and no errors were found.

 

On your second suggestion, I ran the “repair” option first but found nothing to repair. So, I did reset the windows security and did not solve the problem.

Do you have any system restore points that are previous to you making the changes.

Hello, phillpower2

 

yes, I did. Sorry , I forgot to mentioned in my original post. After, the system restoration the problem was not solved....I had not made any changes to my system prior to notiicing the problem. 

 

that's a major reason why i'm here asking for help

 

Thank You phillpower2

An in-place upgrade would repair any Windows drivers, and updating the drivers from the Dell website should replace any corrupt/missing files.

 

Have you updated the drivers using the detection tool on Dell's website?

Question if I may, did you receive this PC with Windows 11 pre installed by Dell or have you manually updated to 11 from Windows 10 yourself.

 

Do a reset from within Windows 11; choose the Keep my files > Change settings > Preinstalled apps On option " How to " here

 

If the problem remains it would suggest a third party driver as opposed to a Windows issue.

 

Create a new system restore point then; Let Dell automatically find driver updates for you

Hello philpower and freeBooter..........

 

my Dell system came with windows 11 installed.

 

I did a Dell system scan and it found no problems and only a dell installation application driver.

 

As for a windows reset, I will first try what freeBooter suggested. since it seems the easier alternative for me, at this moment.   I'm disabled and if it works I wont need to reinstall all my current apps.  Last time I performed a windows reset. I lost all my data for a couple of games I had been playing which these are presently installed. if it does not work than i'll probably have no choice but to do a windows reset....

 

A question that i have ,  can I run the windows ISO in windows or do I have to use a USB thumb drive or a dvd disc.to do it.

 

Thanks to both for helping me.....

Hello FreeBooster...

 

on your first reply to my original posting.  you suggested for me to do repair install of Windows 11 by performing an in-place upgrade.  

 

i downloaded the windows 11 ISO to my windows desktop.  my question is, can i run the ISO file directly from my windows 11 desktop or do i have to transfer the ISO file to a USB drive or dvd disc and then run the file from there.

 

thank you

Hello philpower and freeBooter..........

 

Last Sunday I did a repair install of windows 11. after it was all done my problem was fixed and I was able to switch on the memory integrity. I waited a couple of days to report the outcome of the repair just in case my problem would somehow return. As of today, the memory integrity is still on.

 

Thanks to both for helping me.....
