This is OEM software, however, so there are a bunch of caveats. First, it's supposed to be sold for pre-installation on a new personal computer for resale. The system builder is supposed to provide tech support. That means, if you install it yourself, you can't get any support from Microsoft.
The license does not allow transferring the operating system from one PC to another. That doesn't mean you can't do it, but it does mean that technically you can't do so legally (and you'd probably have to call for re-activation as well).
You have to do a full install as well. There are no upgrade versions. Personally, I prefer a full, clean install anyway, but that's just me. It would mean having to restore all the programs and data that were loaded on the computer, but that's not a big deal for many (just time-consuming).
Also, the OEM versions do not supply both 32- and 64-bit versions on the DVD. They only supply one of them, which is, once again, not really that big a deal.
