By the way, if any of you don't know how to make 'TrustedInstaller' the owner of a file (or folder), type in 'NT SERVICE\TRUSTEDINSTALLER' (without the quotes) where/when it asks to input a user name for owner of file (or folder).

======================

The default owner of the DLL files which need to be replaced (dwmcore.dll + uDWM.dll) is TrustedInstaller, which is the reason for this post.  I like to set the owner back to TrustedInstaller after I grant myself read/write access and/or replace (or modify) these system DLL files.  Ergo, this post is for those of you who wish to change owner of, or, add read/write access to a file and/or folder using Windows Explorer to TrustedInstaller, yet, are unable to (because just typing 'TRUSTEDINSTALLER' in the input box won't work).

You can also use a program called RunAsTI which spawns a CMD with Trusted Installer rights, that way you can replace the files without changing the owner.

Hello guys.  Thanks for the workaround provided, but I am unable to get it to work.  I've tried RunAsTI and manually change the ownership of the two files to myself, but I can't copy the two .dll files over because it says they're in use.  I know that RunAsTi and the changing the ownership work because if I don't use that, I get a permission error instead of file in use error.  The files are in use by DWM.  I have not found a way to stop DWM as it keeps restarting if I End Process.  I've even tried in Safe Mode with Command Prompt only but DWM still runs in that mode.  How are you able to copy those .dll files over?   I can't find DWM in the services.msc to stop the auto restart (as per many Google search suggestions).

Renaming original files should work.
