The KB Patch that I mentioned was for Winodws 10. Windows 7 and Windows 8 had different KB numbers (And there were quite a few, I don't know them by heart). But, you can tell which ones they are, as they were installed around September 7h to the 16th.
Unless TnC isn't starting by displaying a Japanese textbox that starts with "Administrator", you shouldn't uninstall KB patches just to be on the safe side.
Also, check out the other TnC Thread for other suggestions based on what you wrote there. ^^
