I am often asked whether or not a customer should upgrade to Windows 10. Up until July 29th, 2016, the upgrade is free. While it is definitely worth considering, there are some reasons you may not want to. On a personal note, when I upgraded to Windows 10 on my Mac running boot camp, I got stuck in a BSOD until I reverted back to Windows 7. In the following link CNET explains why it may not be in your best interest to upgrade and what you should consider, http://www.cnet.com/how-to/5-reasons-not-to-upgrade-to-windows-10/.
