The thing is, I installed a program that changed the language of my OS (it was in English and I'm Brazilian), then made the mistake of replacing the files that were in English and then I was replacing the files in Portuguese that I have recorded on a CD-ROM, SFC.exe used the program for this, then replace the Explorer.exe Explorer.exe in English by the Portuguese, did it also with the User.exe and Systray.exe. But it did not work, but before I do these replacements on a single floppy these three files in the English language. Now I'm back both these files to their proper places, apart from the Portuguese language and putting the English Language. But when I give the command at the prompt to perform the replacement of the message: ACCESS DENIED. What do I not access denied? In short: - Explorer.exe is in Portuguese and English in HD on the diskette - User.exe in HD is in Portuguese and English on the diskette - Systray.exe in HD is in Portuguese and English on the diskette My goal: - Remove these three programs in HD that are in Portuguese, and put the language back to English HD - Error message that is giving to perform the replacement: ACCESS DENIED PS: Sorry if you have something wrong, I'm using Google translator to write this message, and also by the size of the message. I hope you understand.
