Hi Craig, thank you for the info
Just wanted to mention that about computer related issues I am computer science graduate, with msc etc
programmer I use computers from dos 3.3 so I had all version of dos and windows the last 30years
So my opinion was based on benchmark (my passmark benchmark - a very known computer benchmark, was slower after the update).
Generally on every large scale update windows become safer, visually improved and little bit slower in the same processor. Just processors become faster and faster and so that's not a problem.
Also if someone have an ssd hard disk that is a very fast hard disk, it's not allowed to do defrag, It may destroy the disk
