It is best to do a manual update to Win10. It is painless and straight forward for any activated Win PC. But there will come a time when you encounter problems and Micrsoft or any "gurus" that sprung up like mushrooms within a day or 2 of the official release advised to "reset". Even if you have to reset select "maintain your existing file" rather than "clear the existing apps, settings, files". I am talking through experience here where my keyboard/mouse/USB drivers are not loaded after Win10 reset, therefore leaving me stuck staring at the "lock screen". I can do a format and reinstall Win10 with the risk of not getting the copy of Win10 not activated. Because the Serial number of Win10 is a generic number from my Win PC, I had checked on my 1- Win7 (same number), 3- Win8.1 (same number) except the product ID is different. These number cannot be used as "your own" copy serial number. Whatever you DO NOT RESET your Win10 (bcoz any marginal compatible/updated drivers) will be deleted. So now I have to down grade back to my previous Win 7 Ultimate version update all the drivers back and do a manual update to Win 10 again after Win7 is activated.(Fingers crossed)

ASC Ultimate and ASC has my PC go bonkers. First my complain was on IOBit Start Menu 8 that locks my PC in just Win7 style Menu and cannt get back to modern UI.(a few months back) Then this ASC Ultimate/ASC also made my modern UI Win10 inaccessible again, only stuck in normal screen mode. So I uninstall but still again like in my previous experience still not able to access my Modern Ui and the Windows Store will not run. Lucy that I made an "image" backup while it was still OK so I restored and got everything back to normalbut without the ASC Ultimate/ASC. Looking around for other apps. But honestly the options for ASC is great if you want to risk not being able to access Win Store and Modern UI.

Upload speed compared to GoogleDrive or Dropbox is horrendous.
It always cause my PC to startup slowly or crash and I did uninstall it once and solved my crashes or not let it startup with Windows to solve the problem.
