Google - I cannot open my encrypted files after I formatted my laptop, but I have my old "windows"?

you should go into system recovery every computer should have system restore on there you can go back to a earlier time or you can restore from your boot up the windows copy should be on the bottom of your laptop or tablet or desktop computer this will set your computer to the default levels it started with your authenication code would be on the bottom or windows installation disk if you have one if you don't copy the code and then install windows that way
