I was pleasantly surprised how much easier windows was to install the other week, I'm mac through and through but we do have 3x gaming PCs in the house for the kids. All needed more space so we decided to move to SSD for the OS. I had previously upgraded each one to Windows 10 Pro via my microsoft account which manages licences for our OS's and Office etc. I new windows can't easily be transferred to another drive so decided on a fresh install. Downloaded the OS from MS onto a memory stick, swapped the HDD for the new SSD and booted with the stick. It sailed through and licensed its self from the Device ID it had for the machine which was a nice surprise as i was expecting a right load of messing.
