Download R 2.15.1 for Windows (47 megabytes, 32/64 bit)
If you want to double-check that the package you have downloaded exactly matches the package distributed by R, you can compare the md5sum of the .exe to the true fingerprint. You will need a version of md5sum for windows: both graphical and command line versions are available.
Please see the R FAQ for general information about R and the R Windows FAQ for Windows-specific information.
