I need Test Mode on, but don't want the ugly watermark. I have Windows 8 Home Premium 64 bit Build 9200. I am trying to remove Test Mode from my desktop, but when I edit shell32.dll.mui, it won't let me save it. If I save it to the desktop, I can copy it over to the original folder, but when I open to check if strings are still gone, they are back! If I copy it back out, they are magically gone again! I have complete ownership of the file. Please help. Any suggestions?
