1. Do these:
a. Open windows explorer and nativate to the C:\WINDOWS\SYSTEM32 directory.
b. Right click on SFC_OS.DLL and click copy.
c. right click in directory anywhere that is NOT on a file.
d. It will create a new file with a name something like "copy of SFC_OS.DLL".
e. Right click on that new file and select RENAME.
f. Type a new file name. Something like "BACKUP_SFC_OS.DLL".
You have just made a backup (e.g. copy of the file) with a new name.
2. Do this:
a. Do same thing as step 1, but give the new file name "SFC_OS1.DLL".
b. You don't that I know of have a hex editor built in to windows. You'll have to download and install one. A hex editor that I like is called febooti because it integrates into your File Explorer properties dialog.
c. Go to http://www.febooti.com/products/file...rs/hex-editor/
and download/install febooti.
d. Once febooti is installed, you can get to it through file properties in Windows Explorer.
e. Right click on the file "SFC_OS1.DLL" and select properties.
f. There is now a "Hex Editor" tab in that dialog box.
g. Make any changes it tells you to in that hex code and click OK.
h. When it closes, it will ask you if you want to save the file. Select "yes".
