That is very likely pirated material (not legit). Tom's Hardware does not support any form of software piracy. None. Period.
Just because it "works" does not mean you should use it.
Just for saving free space in the HDD. For Example Windows Vista iso files (estimated file size):
Windows Vista Starter x86 2 GB
Windows Vista Home Basic x86 2 GB
Windows Vista Home Premium x86 2 GB
Windows Vista Business x86 2 GB
Windows Vista Ultimate 2 GB
Windows Vista Home Basic x64 3 GB
Windows Vista Home Premium x64 3 GB
Windows Vista Business x64 3 GB
Windows Vista Ultimate 3 GB
Total 22 GB
Windows Vista x86 Aio File Size : 2,76 GB
Windows Vista x64 Aio File Size : 3,45 GB
Whould you rather 6,21 GB File or 22 GB File? Everything is same, only file size is different.
