Nice work. This is an awesome idea - if you add more checksums for other versions of Windows it will be very popular.
The original SP1 checksums are not in the Windows RTM ISO Verifier XML files because you shouldn't be using them. They have been removed from Microsoft's website and have been replaced with the Media Refresh. The links are only still active to be used at your own risk. Sorry but the old images are now unsupported. Only Media Refresh is supported. But yes anything from digitalriver is legit!
jlgager, when i run the standalone EXE the software works fine. when i run the Extracted version i keep getting the language file not found error. YES the LanguageList.xml and English.xml are in the same directory as the EXE. no matter what i do it keeps getting the error. i would like to use the Extracted version so i can add other hashes to the xml. is it me or is there a bug in the Extracted EXE ?
