You will need to take ownership
and set permissions
to "Allow" your account "Full Control" of the original file
in your current installation before you will be allowed to replace it with the extracted copy.
If the system file is in use and you are unable to replace it with the extracted copy, then:
Copy /Y "full path of extracted replacement file" "full path of original Windows 7 system file" For example:
- Open a Command Prompt at boot.
- Do steps 4B to 4D in this tutorial first to verify the drive letter of your Windows 7 drive. It's not always C: at boot.
- Type in the command below to copy and replace the original file with the extracted replacement file.
If the extracted replacement uDWM.DLL
is on my desktop, then I would use type this in the command prompt at boot and press enter. Copy /Y "C:\Users\User-name\Desktop\uDWM.dll" "C:\Windows\System32\uDWM.dll"
