This means that this driver allows the direct access to the internal hardware from the CPU itself. For those who are curious, fltmgr.sys is located in C:\Windows\System32\drivers.

Run " sfc/scannow " and run " chkdsk c: /f /r " to check and repair disk errors on your C drive

ok running this now to test - after will see if it crashes again, i had to reset 2 laptops because i could't figure out how to remove the update, it did not show that the update was installed on the computer

In addition to all the above, be sure to update BIOS (Lenovo DOES have BIOS updates), Chipset and all other drives (Lenovo System Update and replicate the idea on Dell).  

Restart and try updating again.

yes i did all the system updates with the lenovo software and dell also - it was crashing during the updates hahaha
JohnBusiness Consultant (Owner)Commented:
Then there may be some legacy software conflicting ?  Possibility to consider.

Open cmd.exe with Run as Administrator and run:

1. SFC /SCANNOW.  Allow it to complete.
2. dism.exe  /online  /cleanup-image   /restorehealth

Once all is complete, restart and test.

This update KB4494440 is for OS Build 14393.2969
https://support.microsoft.com/en-ca/help/4494440/windows-10-update-kb4494440

That is version 1607 which is long out of date unless LTSB

running sfc /scannow and chkdsk did not work -

Assuming you can get the machines to run even briefly, try a Windows 10 Repair Install and see if it will update

https://www.microsoft.com/en-us/software-download/windows10

Windows 10 is running, so click on the Download button (not Upgrade Button, select Save.
Create a USB Windows Installation key and then run Setup on the USB Key.
This will launch the Repair and proceed normally.

How many machines do this?  

In most of the cases I have seen with this blue screen error, the computer needs to be re-imaged.

22 of my computers, both Lenovo laptops and Dell workstations

Try the fixes noted in this article below

The error still points to drivers.
