If you've already reinstalled Windows 10 on your Mac then be sure to download the latest Windows support software from the Boot Camp tool to ensure you have the latest drivers.

Many people may have 32-bit versions of Windows Vista installed, and may opt to go directly to the 64-bit version of Windows 7 given the trend in 64-bit software becoming more available.
Unfortunately, if you install the 32-bit version of Windows 7 you will not be able to upgrade to the 64-bit version and will have to perform a clean install.
You can do this by installing NTFS-3G and then cloning the Windows installation from the Mac side (the utility Win Clone is a good option for this), or you can do this by running a cloning program from within Windows.
At the very least, be sure to back up your Windows files before upgrading. If you are sick of having windows on your system, you can easily remove it and have just OS X on your system.
You’ll be able to install Windows 10 on that same Mac in the future.
