Fixes for missing DLL after Windows 10 update December 2015

[Secici]

Hi! My computer just updated Windows 10 and .... lots of errors loading. Missing DLLs again that I thought I fixed already. This happens with European windows not having these DLLs due to international copyright problems. These are the missing files:

WMASF.DLL
WMVCore.DLL
mfperfhelper.dll

This is the fix (If you had them before the patch):

1. Go to your File Explorer > This PC > C: > Windows.old > WINDOWS

These files live in two places: System32 and SysWOW64. System32 is generally DX11, and SysWoW64 is DX9, or so it seems to me.

2. Search for these files using File Explorer

3. Copy the file. Right Click it off the list and selecting 'Copy'

4. Use File Explorer again: This PC >C: >Windows

then paste to System32 or SysWOW64. This will usually require administrative permission on your machine.

Try this for each of the missing DLLs and you might be ready to go again.
I would NOT recommend reinstalling FFXIV since that is not likely to fix Windows errors.
