I have a Keian's tablet PC KBM100K (windows 10 64bit ,emmc 32GB). And it had encounterd a difficulty of majar windows update by shortage of storage capacity of C drive. So I did clean installtion of windows 10 into my tablet.
But unfortunately a code 10 error occured at the wifi device driver for Broadcom 802.11ac WDI SDIO Adapter.
After many struggles, I could fix that problem. So Irecord the measures.

(Only Japanese languaage available ) Then download KBM100K、KBM85B WiFi,Bluetooth ドライバー.

'4.1 Save device drivers inside of the tablet PC in backup. This will be helpful for recovery the device drivers, because it might be difficult that these drivers will be got from another places.
例: windowsにあるdismコマンドで退避
e.g. Save them by using windows' 'dism' command.
mkdir D:\DriversBackupdism /online /export-driver /destination:"D:\DriversBackup"
