How to Calculate a File's Checksum
Download the FCIV file from the Microsoft website (see link in the Resources section) and save it on your computer.
Double-click the file to extract it. Save the file in C:\windows\system32\.
Go to the Start menu and type “cmd” (without quotations) in the Run or “Search for programs and files” field and press “Enter.”
Navigate to the folder hosting the file.
Type “fciv filename” (without quotations, and substituting the name of the file you wish to check) and press “Enter” to create the MD5 checksum.
Type “fciv –sha1 filename” and press “Enter” to create the SHA1 checksum.
Compare the checksum with the one provided with the file.
