11. Now open the numbered folder (step 8) that is the same edition as your currently installed Windows 7 edition, and navigate to the Windows\System32 folder. You can now select and extract the system files that you need to your desktop. (See screenshot below)

12. Verify that each extracted file is unblocked. You can now use the extracted files to copy and replace your missing or corrupted system files in your currently installed Windows 7.

   Tip

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:

• Open a Command Prompt at boot.
• Do steps 2B to 2D 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.

Copy /Y "full path of extracted replacement file" "full path of original Windows 7 system file"

For example:
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"
