I bit the bullet on Feb 20th to go from a rock solid Win7 to Win10. I followed the procedure mentioned in the video and did not have a problem. All of my previous software continues to work without any issues. I have a fast internet connection and the whole ‘nail-biting’ process took about 4 hours. It will reboot a couple of times but don’t start this update and walk away, as you will need to make a couple of choices at the beginning. After it finished completely, I checked to see if the new Win10 was ‘verified’ and it wasn’t until I shut down and rebooted manually. Then it show up as verified. Good luck.
