Any updates on this? I had a hard drive crash, rebuilt the system with the restore disk that came with the computer (WinXP Tablet, SP2), and can't get this to work. I'm pretty sure it was working before. No matter how many ways I delete/move/copy/rename notepad.exe in /windows, /windows/system32/ and /windows/system32/dllcache, I can't get it to stick. The file reverts immediately.
I've also edited filelist.xml as described in http://blogs.msdn.com/omars/archive/200 ... 24093.aspx
. This did not help. I stopped short of doing a binary edit of a system dll and registry edit to disable system file protection. (Sorry, I can't find the link for that page now)
Okay, I think I licked this. I deleted /windows/i386/notepad.ex_ , after making a copy of it first. (I didn't just rename it, as I don't trust Windows to respect what I'm doing at this point.) Then I could replace notepad.exe in the three locations indicated above, and it seems to work. I didn't try copying the new and improved notepad.exe to notepad.ex_ there...that might make things go smoother, I don't know.
If that doesn't work for you, search for folders named "i386" on your system. See if it (they?) have a notepad.exe or notepad.ex_ file. It seems this folder can exist in different places depending on your vendor and possibly other factors? Make sure to search for hidden and system files (under advanced search options).
If that doesn't pan out, search for notepad.* across your whole system and see how that goes.
