He lost all plausibility when he said Microsoft were doing it so we would all go out and buy new laptops or tablets. Apart from the licenses, how do Microsoft benefit from the sales of new computers?
If you spend a little time running Disk Cleanup after each update, Windows will process the background tasks that it needs to and free up your computers resources. I agree you shouldn't need to do this, but it's a workaround that works for me.
Yeah he is pretty uninformed verging on conspiracy nut - it isn't a great video itself but the comments are another example that there is a not insignificant number of people that aren't actually very happy with Windows 10 and mostly for reasons that are completely in MS's hands to fix.
