As I understand it, if a file is open, e.g. C:\perl\lib\CPAN.pm, that file can't be deleted by Windows. You can install a newer version as C:\perl\site\lib\CPAN.pm, but @INC lists C:\perl\lib before C:\perl\site\lib, so you'll wind up using the older version when you think you're using the newer one.

demerphq's patch (not yet on CPAN) uses Win32 API calls that effectively rename the open file, install the new file in place of the old one, and schedule the renamed old file for deletion upon next reboot. (Ever see how Windows install/uninstall programs tell you they can't complete until rebooting? Same thing.)
