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.

Here's my Dell XPS 8700  config.

    You can also run the dism cmds via the boot media too.

    You can run sfc from the boot media, have you tried this?

    If you have then I’m sorry but I’m out of options.

    The repair I mentioned cannot be used unless you can boot in to Windows.

    You can try this:

    No offense, I appreciate help, but my initial note said I couldn't boot and the link you provided talks about running DISM and SFC which I've already done.

    I'm looking to find if there is anything I can do to overcome the errors reported in the SFC in relation to ACPIEX.

    Did some more digging. This is the first 3 lines of the SFC log file which seems to say it's assuming AMD rather than INTEL.

    00000001 Shim considered [l:125]'??\d:\windows\Servicing\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.18362.590_none_5efc551459114cb9\wcp.dll' : got STATUS_OBJECT_PATH_NOT_FOUND

    00000002 Shim considered [l:122]'??\d:\windows\WinSxS\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.18362.590_none_5efc551459114cb9\wcp.dll' : got STATUS_SUCCESS

    00000001@2020/2/23:15:30:21.965 WcpInitialize: wcp.dll version 10.0.18362.590 (WinBuild.160101.0800)

    00000002 CSI Store 1689281814864 initialized

    However, it looks like this is instruction set and according to this posting, AMD was the first to come out with 64 bit and Intel adopted that instruction set.
