The MD5 Checksum is used to check the integrity of the ISO image you
download, if it does not match the ones I posted earlier, the build is
probably corrupted.
Paste the MD5 Checksum for either x64 or x86 depending on which one you want
to
check in Step 1, Step 2 - Browse to where you stored the ISO on your drive
and open it and it will automatically start the verification process and
generate the result in the third field, if it matches Step 1, then you are
safe.
