Concerning the Windows 7 Repository: Having done this wrong the first time, might I suggest the addition of a caution to check the hashes prior to unlocking all the editions, as this will produce a different hash. With hindsight it makes a lot of sense. To summarize, the order of steps should be 1) Download the ISO of the version you want (32bit or 64bit). 2) Scan downloaded file for viruses. 3) Check the Hashes. 4) Unlock the other editions using ei.cfg Removal tool (optional). 5) Burn the Iso to disk. 6) Install windows. 7) Activate Windows using your preffered method: Bios Mod or a Loader. I'm not saying to add all of this text, just a simple caution at the point The Official Windows 7 Repository mentions unlocking the other editions.
