How can I reinstall Windows 7 if I lost my installation DVD?

I need to reformat my computer, but I don't have my OS discs with me (I do have the cd keys, though). Can I burn a pirated copy of the OS, and then install using my legit cd keys?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Pirated software is known to include viruses and SpyWare. Don't ever use or copy pirated software, not only for this reason, but also because it's wrong. – Randolf Richardson Jun 17 '11 at 17:58
@Randolf is right in that we don't encourage or condone piracy here. Consensus is that anything that breaks an EULA isn't encouraged, I believe, and I agree wholeheartedly with this. (It would probably open StackExchange up to litigation, anyway.) – Shinrai Jun 17 '11 at 19:13
It's a technical question, not an ethical one. The ethics are debatable, of course. But that wasn't really the question. – DA. Jun 17 '11 at 20:23
@DA: The inclusion of the words "using a pirated CD" in the question is of great concern as it shows intent to [at least temporarily] violate Microsoft's copyright. – Randolf Richardson Jun 17 '11 at 20:33

There's no need to pirate; you can download the ISOs for Windows 7 installation media directly from Microsoft (well, okay, Digital River's hosting the download but whatever), free of charge.

32-bit Windows 7 Home Premium

64-bit Windows 7 Home Premium

32-bit Windows 7 Professional

64-bit Windows 7 Professional

Links taken from here. I can't personally confirm they're live, but I've done this in the past and they look the same as I remember.

EDIT: Removed Ultimate links since they appear to be dead, but they're out there. Somebody feel free to comment and/or edit these in.

Here is a aggregated list of all of the windows 7 versions from digital river… in case you need a version other than english. – Scott Chamberlain Jun 17 '11 at 17:37
@Randolf - Digital River is a reputable digital file distribution source, used by tons of big name companies. (I wouldn't trust anything that directs to an IP address, for sure, which is why I only posted those and added the disclaimer.) These aren't linked directly on to my knowledge because these are the download links you get if you buy a license key from Digital River - they're not EXACTLY intended for public dissemination, but they're legit and perfectly legal. – Shinrai Jun 17 '11 at 17:42
@Tory - I don't expect anyone to take my word for it if they've never heard of the company (which frankly surprises me, that's like never having heard of Amazon), but I think a quick Google search should clear up any concerns about Digital River specifically (and the domain is, of course, registered to their corporate entity). – Shinrai Jun 17 '11 at 17:47
@Randolf: When I bought a digital copy of Windows 7 from my school, they linked me to Digital River. So I think it's legit. – BlueRaja - Danny Pflughoeft Jun 17 '11 at 19:26
@RandolfRichardson I can confirm that Digital River is Microsoft's official distributor for installation media purchased online. I have done this before when buying Windows directly from Microsoft. These links are legitimate, and publicly accessible and known. In a similar vein, see is discussion of removing DRM permitted? on meta. – nhinkle Jun 17 '11 at 20:59

That would work however this is what Microsoft recommends.

Legally and ethically, this is the best answer for this question. +1 from me. – Kirk Jun 17 '11 at 18:16
+1 from me too for the same reason -- emphasizing the ethical choice is always paramount. – Randolf Richardson Jun 17 '11 at 20:10
