Running a 3 year old Lenovo Laptop with 8GB of RAM that started off with Win8, and is now on Win10
Use it every day for work, and it's not a problem. All the machines at work are also Win 10
I've set it up so that all my common programmes (Firefox, Thunderbird, Word, Excel, Memory Map, EndNote, PDF Exchange, Cyclo Agent and OneNote) are along the Taskbar so I hardly use the Start menu. Much easier that way...
