Microsoft don't provide a download for Windows installations unfortunately. The Vendor will probably try and charge you for a copy of the clean media or send you out their recovery CD's which will have all their bundled software (crap-ware) You may have a recovery partition on your HDD, a lot of modern PC's / Laptops do. Saves the vendor the cost of the media ;-)
Have a look on your manufacturers website for instructions for your model to re-install the OS.
Otherwise it is Legal to download a copy of Windows either directly or over torrent or borrow a friends DVD and reinstall using your product key that is on your case.
As far as I can tell, no. Not legally, anyway.
I think your best option is the contact the retailer you acquired the computer from and ask for physical media.
You can't. you need to get the installation media from the computer vendor. If the computer came with Windows pre-installed then they should provide the installation media for you.
As a consumer, you can't. However, if you have MSDN membership, you may be able to download it.
