Windows 10: Unsigned .Dll files

I've got a reoccurring issue with my .dll files.

The issue is related to games on my PC that use EAC (Easy Anti Cheat), and every time I launch a game using EAC, I am prompted with Untrusted system file (C:\Windows\System32\a random dll file). I thought the issue might have been related to one game, Apex. But on further attempts to fix the issue, I found that other games that use EAC were also throwing the same "untrusted system file" error, and it's not always the same .dll file.

I have tried the generic SFC scan/repair commands but have had no luck, along with deleting/replacing dll files from system32.

Today I checked my system32 dll files by using CMD & sigcheck, I have found that pretty much every .dll file scanned is marked Unsigned (Example shown below)

Verified: Unsigned
Link date: 2:27 PM 23/01/1917
Publisher: n/a
Company: Microsoft Corporation
Description: Unicode Normalization DLL
Product: Microsoft« Windows« Operating System

I have a support ticket opened through EAC, but their replies take days.
Any help is appreciated, here's hoping I don't need to re-install windows.

.DLL file

Hi Jerry,

Specific programs use DLL files to function properly in a Windows environment. If the DLL file gets misplaced, deleted, or corrupted, the error "____.dll is missing" appears. We'd like to learn more about your concern so that we could provide
the proper resolution. We just have a few questions for you:

• Which build version of Windows 10 is on your computer? To check, click
  Start, type winver, and press Enter. For example, 14393.1066.
• Did you make any changes to your computer before this started happening, like installing or uninstalling a program?
• What troubleshooting steps have you done so far?

As an initial recommendation, we suggest that you disable your Startup programs to isolate the cause of the error. To do this, follow these steps:

• Right-click the taskbar and select Task Manager.
• Click More details.
• Go to the Startup tab.
• Right-click every listed program and choose Disable.
• Restart your computer and check if the issue persists.
  
• If the error disappears, enable one of the programs and restart your computer to check if the error reappears; this is to pinpoint exactly which program is causing the error. Do this for all Startup programs until you find the cause.
• Once you've found the program that's causing the error, you can then try uninstalling and reinstalling it.

We'll wait for your response and the results of the troubleshooting.

dll file not found after Creator's Update, Code Execution Cannot Proceed

Hi Aberfoyle,

It is possible that the
.dll file was corrupted during the update causing the error to occur.
To better assist you, kindly find the
.dll file
in
c:\Windows\System32. If you can find the
.dll file, it means that we need to
register
your
.dll file
to your
Operating System
for it to
work. To do this, we need to
unregister
the
.dll file
first and
re-register
it. Here are the steps on how to do so:

To unregister the .dll file:

• 
  Press
  Windows key + R, type
  Regsvr32 /u c:\Windows\System32\VCRUNTIME140.dll
  and hit
  Enter/OK.
  

To re-register the .dll file:

• 
  Press
  Windows key + R, type
  Regsvr32 c:\Windows\System32\VCRUNTIME140.dll
  and hit
  Enter/OK.
  

If you cannot find the
.dll
file in
c:\Windows\System32,
kindly run these methods of troubleshooting
so that we will know if the issue is within/not within the
Operating System:

Method 1:
Run SFC Scan.  

SFC
will
scan
and
run
an
automatic repair
to any
corrupted system files
that it will detect. We suggest that you perform it twice. To run an
SFC scan, follow these steps:  

• 
  Run
  Command Prompt as Administrator.  
  
• 
  Type
  sfc /scannow
  and hit
  Enter.   
  

Note:
Kindly run
SFC twice or thrice
and check for results before you proceed to the next method.

Method 2: Clean Boot.

Clean Boot
will
stop or disable
the
applications
that are running in your
computer's background.
To perform a
Clean Boot, click
here.

Note:
Reset the computer back to
Normal Mode
once you are done with the troubleshooting by following the section
"How to reset the computer to start normally after clean boot troubleshooting"
from the same article.

After performing these
methods of troubleshooting
and still the issue persists, we suggest that you contact your
computer/laptop manufacturer
for further assistance.

Update us on how it goes.
