how to download bootcamp drivers windows 10

My bluetooth chipset information is Broadcom USB 20702A3.Boot Camp requires a Mac with an Intel processor. Or Is there a way to download the bluetooth drivers alone from apple site. Or can I create the '$WinPEDriver$' folder manually, just as BootCamp Assitant creates it. I live in a place where bandwidth is very low, so downloading another 2 GB of drivers will take 3 more days, and may also get interrupted frequently.

Is there a way were I can download the '$WinPEDriver$' folder alone from Apple site. I tried to install the Bluetooth driver alone manually, that also didn't help.

With this the driver installation does proceed, but everything except the Broadcom_Bluetooth_Driver are getting installed. So I created a empty folder named '$WinPEDriver$'. When I try to manually start the setup.exe in BootCamp folder, it quits saying '$WinPEDriver$' folder is missing. Without '$WinPEDriver$' folder, Windows10 get installed without the drivers. Now I wish to reinstall it, but when I took a backup of the bootcamp drivers, I only backed up the 'BootCamp' folder, I forgot to backup the '$WinPEDriver$' folder. Then due to space issues I deleted the Windows partition, thinking I can always reinstall it, if needed.

I was able to use it to install Windows10 and use it.

I also downloaded the bootcamp drivers, and a folder named 'BootCamp' and '$WinPEDriver$' were created in my Windows10 bootable usb. I have an macbook air 2012, I recently installed Windows 10 in it using bootcamp.
