I want to install Windows 10 for the first time on my PC which is currently running Win 7 Ultimate with MSDN license. I will use "MDL-provided activation" , so the retail price will not be an issue here. I have installed my current copy of Win7 five years ago and used it until this month without much pain, so I have not looked elsewhere. I am out of the loop so forgive me if my questions seem trivial. I just want to make sure that I pick what I need and I have after the Win10 install at least another five years of problem free Windows mileage. I consider myself a lazy power user who if necessary can find the time and energy to dig deep in the system (editing registry and scripts) but wants to avoid such things if possible and keep everything vanilla and problem free as long as possible. The less hacks and headache the better. In my free time i like to: -Play video games -Hobby level software development (Visual Studio) -Playing with virtualization (VMware Hypervisor on WMware Workstation ad the like) server and networking The chosen edition should: -Easy fool proof and robust activation -As little as possible chance that the activation gets patched out. -Contain as little as possible bloatware -Support the things I want to use it for (above) -I would prefer to have the minimum level of telemetry collection, but it is not a top priority, I dont want to hack it out of the system if that breaks future updates. -Allow my to upgrade my current system (Intel Ivy Bridge at present) at a later time So the questions are : -which edition should I get? -and where to download from the original unchanged ISO files? -Which activator to use? Thanks in advance! J.
