to the list of Excluded files. Now you should be able to overwrite notepad.exe.
You can also try the following to get around System File Protection. Be very quick or XP will replace the file and it won't work. Make sure you don't have the WinXP CD-ROM in your drive!
1) Copy metapad renamed as Notepad.exe to the clipboard.
2) Go to C:\WINDOWS\System32\dllcache
3) Paste the file there.
4) Go to C:\WINDOWS\System32 (using Backspace)
5) Paste the file there.
6) QUICKLY! Go back to C:\WINDOWS (another Backspace) and paste the file there.
If you have done this correctly, a message should pop up saying that a bad version of a Windows System file has been installed. Make sure you select 'Keep this file' or a similar option. If it doesn't work, keep trying, because it will. Just do the two pastes very fast.
