Well, I upgraded my MacBook Pro to Windows 10 from Windows 8.1 the first day it was launched, and the upgrade went without any issue. I only had to reinstall Boot Camp drivers after upgrading (brightness and volume keys were not working properly), but after that Windows 10 worked just like Windows 8.1.

Has anyone upgraded their existing Bootcamp partition to Windows 10? I am running Windows 7 on a 2011 27inch iMac. Will an install delete my already installed partition or should I download the iso from Microsoft and run Bootcamp again?
Make sure you have installed all important and optional updates through Windows Update. Note that you have to be running Windows 7 Service Pack 1 too.
