I have removed the link to the download. We do not allow the distribution of Windows ISOs, even if they are fake :)

Now for your question, that is not a real Windows ISO. The ISO does consist of files that are named the same as those on the legitimate Windows ISO, but the files themselves are filled only with NULL characters. This serves to increase the file size, but are able to be compressed down to almost nothing when compressed.

Best way to describe it is that the file in that ISO are like baloons filled with air. Once the air is removed they are quite small.
