Since that is a Windows file (part of the Microsoft Foundation Classes library) it's likely that Windows' SFC (System File Checker) utility will restore it.
 
It might also be worthwhile to do a deeper system check using the DISM tool, e.g.
    c:\dism /online /cleanup-image /scanhealth
This will take awhile to run, but it will verify the backup copies of system files that SFC uses to fix problems.

So funny thing... well I'm use to BS like this. lol
Recording most of the day and not one crash or audio drop with 2017 10 BTW. Nice JOB to the Bakers on that. :)
 
I'm going over the tracks I recorded. With out any reason, not being connected to the internet, not doing anything out of the norm on this 2 month old Win 10 system... The sound stops in Splat. I exit. No sound in windows as well and like I said I was working all all day...
I reboot. still nothing. I check everything its all ok. I then go into the Device manger and everything related to audio as well as my Wifi that I had uninstalled when I got the system where all set back to default. Onboard Audio drivers where reinstalled. I deleted them and rebooted. they cam back. I went into control panel / sound I and there where 4 output options and 4 input options. all enabled. A few other things I had set had changed as well. so I deleted everything except my Tascam US1200 rebooted and everything was fine again.
I did downloaded Splat and updated Virus ware, well before working but unplugged the net cable.
Win 10 Shows no updates. 
 
I don't get it...
 

mfc110u.dll was not found
 
This happens if you're c++ 2013 r library gets hosed up. You need to to go to Microsoft's website and download the fix for it both 32 & 64 bit. Run the fix, reboot, and you should be OK.

I believe you are correct sir.
 
There are other possibility's that have lead us to hear.
For example:
- Using Ccleaner's "Registry clean" function. It can remove components from redundant entries that are needed to run other programs.
- Windows update is not up to date or has become corrupt.
- A virus or malware is using a duplicate / or the original MCF100 as a host for running a logger or something of the equivalent.
- A hardware failure- Hard drive on its way out the door/corrupt sectors.

That was the culprit for me about 6 months ago, I googled the missing dll file and that lead to the C++ fix. I went here:

Clicked download and ran the installer, it gave me the option to repair. That did the trick.

This caught me out on Friday on my work pc (which I don't use for SONAR)
It removed a couple of reg entries which prevented Sage 50 Accounts from running.
I didn't tell my boss, just reinstalled Sage 

Thank you all for your inputs.
I however solved  the problem by restoring the computer to a pre-update date.
Everything is now working fine.
