I have a late 2011 Macbook Bro. It had Lion 10.7.4. I installed Windows 7 64-bit with Bootcamp but I installed it without the windows support files or software. I thought that I would be able to download the windows support software latr on, but I cant find it no where. Now each time I restart my Macbook it goes directly to Windows. I have no way of going back to OS. Where can I get the windows support files? Please help.
