For years, Microsoft allowed us to download Windows 7 ISOs. They did it using their content delivery partner, Digital River. On February 2015, the company decided to take down those links. Thankfully, there is an independent mirror where we can download Windows 7 ISOs, legally and for free.

Downloading Windows 7 is convenient
Many of us bought our copy of Windows 7 pre-installed with a new desktop or laptop PC. More often than not, though, the box didn't contain a full Windows 7 DVD.
Usually, we would get a "recovery disk", to reinstate the operating system to its default settings. But this would also reinstate all the bloatware and crapware the manufacturers include. Remember Superfish?
The ability to download Windows 7 ISOs is essential for anyone who wants a clean Windows installation for their PC. It is also handy if we misplaced, lost, or destroyed our original disk.
How is it legal to download Windows 7 as an ISO?
When we buy a copy of Windows 7, we don't get a special installation DVD. Every DVD of a particular version - e.g. Windows 7 Home Premium x64 - is identical to all the others.
What we buy is the unique 25-character product key. We will find it as a sticker on the retail Windows 7 DVD case. Or, with pre-installed Windows, stuck under underneath our laptop and on the side of the PC tower.
With this product key, we can install Windows 7 using any disk of the corresponding version. No matter where we got the Installation DVD, we will end up with legally activated Windows 7 on our PC.
We can even download Windows 7 as an ISO from the shadiest torrent site. As long as we are using our legitimate product key, the Windows installation will be 100% legal.
Where can I find the Windows 7 product key?
If our Windows 7 PC didn't have Windows preinstalled and doesn't have a sticker, we can use special programs to get the Windows 7 product key, even in cases where we can't boot into Windows.
Just check our guide:

Microsoft giveth, Microsoft taketh away
Even though it would work, downloading Windows 7 from questionable sources is never a good idea. For all we know, it could contain a host of malware: rootkits, trojans, keyloggers, you name it.
That's why it was a big deal that Microsoft allowed us to download Windows 7 as an ISO through Digital River. We could download Windows 7 and be sure that the ISO was clean and untampered.
And then, in early February 2015, Microsoft decided to take down the Digital River ISOs, for good.
Sure, they have set up the Microsoft Software Recovery website, the "official" way to download Windows 7.
However, to download Windows 7 through this website, we need the product key of a store-bought, retail version of Windows.
In case we have a desktop or laptop computer with pre-installed Windows 7, we own an OEM Windows 7 License. And Microsoft's website, for reasons unknown, won't let us download Windows 7 ISOs with a valid OEM product key.
So, as OEM owners, what are we supposed to do? Steal a disk? Beg friends and strangers for a Windows 7 DVD?
According to Microsoft, we should order a physical replacement disk, wait a couple of weeks for the delivery, and pay the shipping and handling fees.
Not exactly an ideal solution.
The clean way to download Windows 7
The good news is that whatever goes up on the Internet, never really goes away - for better or for worse.
The German mirror http://mirror.corenoc.de/ has done an exceptional job gathering the Digital River ISOs and uploading them as torrent files. They have all the different English versions and even a few in other languages.
Download Windows 7 torrent
To download Windows 7 using a torrent file, we will need a torrent client. In the example, we will be using the popular torrent client qBittorrent.
With a torrent client installed, we only need to download our preferred version's torrent file:

The torrent file is just a few kilobytes in size, and it will download immediately.
Download Windows 7 with the torrent file
If our torrent client is correctly installed, we just need to double-click on the torrent file, which will start the client, and will ask us where to download the ISO file.
Depending on our internet speed, and the available seeders, the ISO file should download in a few minutes.
How can I trust that these Windows 7 ISOs are clean?
As we mentioned earlier, downloading Windows 7 from questionable sources is never a good idea. So, since a random German mirror site can't be considered a reputable source, how can we be 100% positive that these ISOs are clean and safe?
Fortunately, Microsoft can help with that. You see, these ISOs are the same ISOs we could download if we had an MSDN subscription. And Microsoft provides the SHA-1 checksum for the ISOs downloaded by MSDN subscribers.
We just need to visit this page, where we will find the relevant information for all the Windows 7 ISOs.
We just need to look for the version we downloaded using the torrent file, and click on "Details". For the example, we will be using Windows 7 Home Premium with Service Pack 1 (x64).
- Ignore the Product Keys and Download buttons, they won't work without a 1000$+ MSDN subscription -
We know that we have the correct version from the ISO filename.
To confirm that the ISO we downloaded is 100% clean, we just need to compare Microsoft's SHA-1 checksum with the ISO file's checksum.
For this, we will use the free MD5 & SHA Checksum Utility
This app requires the .NET Framework 3.5, and Windows will prompt to install it if we don't have it already.
Apart from the .NET framework, the app is portable, and it doesn't require an installation. We just run it, click on browse, and select the Windows 7 ISO.
Depending on our CPU speed, calculating the checksums will take a couple of minutes.
On the MSDN page, we select the SHA1 checksum and copy it.
We paste it on the Verify Hash with Generated Hash field on the app and click on Verify.
The "SHA-1 Hash matched" message means that these Windows 7 ISOs are 100% identical to Microsoft's ISOs, and not a single byte is different.
