In this post you’ll find my windows builds of rtl_sdr. The first link is the main branch and this is probably what most people will want. The other links are for keenerd’s experimental branch of rtl-sdr with additional features and the mutability branch - allows direct sampling without a hardware mod - “very experimental - probably broken” according to the author.
