Softpedia has a copy of the W7 SP1 final release 32bit and 64bit for download, I checked the MD5 and SHA1 hashes and they match, do you think this is an unaltered version of OEM final release?
One could assume the hashes were made after any alteration.

Anyone know the reputation of Softpedia? I have downloaded many programs from them and they always come up clean, I store them in a folder for 2-3 weeks, then scan them again before install, paranoid I know.
Edit:
I downloaded the official release from Microsoft, the hashes matched that of Softpedia's download.
