Dateline: July 31st 2015
I have been harping on social media that I would wait a couple of weeks before upgrading the work laptop from Windows 8.1 to Windows 10.
I could not hold on any longer and decided to update it even though I was out in the field.
So I just I installed Windows 10 Single Language on my work machine an ASUS X450L notebook, didn't time the preparation cause I was working. I pressed install 2:24PM, welcome screen by 3:42PM. Not a bad upgrade experience at all. YMMV of course.
