Windows 10: Windows 10 ACPIEX.SYS

I recently upgraded my Dell XPS 8700 see config at end. I had problems getting an upgrade to work. Finally got the upgrade on ISO image to take.


I'd experience several blue screens since the upgrade. Finally, it failed completely saying that the system file \windows\System32\drivers\ACPIEX.SYS was missing or corrupt.


I had both Bitdefender and MalwareBytes installed and suspect one or both could have been causing problems now.


I booted recovery to the command prompt where I ran DISM and SFC. There were no apparent errors in DISM but SFC froze. No disk action; ^C did not work; I had a NOTEPAD window opened but it froze when I tried to open the log file. I was forced to power down the system.


On the reboot I restarted the SFC then noted that Notepad was able to open the zero length SFC_LOG.TXT file where I found the following error.


X:\windows\system32>sfc /scannow /offbootdir=d:\ /offwindir=d:\windows /offlogfile=d:\sfc1_log.txt

Any ideas of how I can get a new copy of ACPIEX.SYS? I'm not sure if it's downloadable since the error seems to imply it is generated.
