I just installed Windows 10 32 bit on my Mini 1012. Everything seemed to work ok except for the Bluetooth. After some searches I got that going as well. Windows 10 doesn't recognize the Bluetooth drivers from Windows 7.
The Broadcom drivers wouldn't work. The installation would just hang.
I found some Lenovo Bluetooth drivers from the Lenovo web site. I used those and it installed generic Bluetooth drivers in the device manager with a yellow mark against the driver to indicate they weren't installed correctly.
I then re-ran the Broadcom driver suite and it installed them correctly. The Bluetooth works ok.
