Hi there

Those testing W10 with Sony VAIO Laptop who have the dual built in SD / Memory stick reader this driver works fine on W10 == am using it on Build 10525 (the latest insider build) W10 Pro.

Memory Card Reader Writer Driver (Realtek) Update version 6.1.7601.92 : Download : Sony India

This will get BOTH cards to work again -- default W10 install only sees the SD card !!! (x-64 version of W10).
