While there are no shortage of people who will lecture you on the evils of pirated software… from the unknown quality (you don’t know if it contains viruses or malware) to the ethical and legal issues (yes, its illegal, even if you are unlikely to get “caught” even in your country).
There are better alternatives, however. Microsoft has a number of programs in which you can get very cheap or even free software if you meet certain conditions. For instance, the DreamSpark program gives you access to commercial versions of Visual Studio and other software for free if you are a student. It’s not the Ultimate version, but it’s the Professional Version.
There is also the Microsoft Student Developer Program.
If you own your own business, and meet certain requirements, there is also the BizSpark and WebsiteSpark programs. This does give you Ultimate access, and if you have your own business (or know someone who does and is willing to foster your membership) then this is a great program. You get it all for 3 years for no cost.
Finally, there are discounts you can get as well from various sources, and you might check with your local Microsoft offices. There is also the ActionPack and ActionPack Development & Design programs, again you have to have a business.. but you can probably find a way to make that work if you’re creative, and legal and ethical, and its software you can trust.
And of course, there is the Community Edition of Visual Studio, which is a fully featured version of VS and free for anyone who isn’t a large business.
