hello,
I just did it. upgrading to win10-1903.
it is the second time I use this method to major windows update (Windows Upgrade Assistant aka WUA) and I think it is one of the best.
- First this WUA comes in as a light exe file and will install itself on root C (as a regular app you are able to uninstall it with ccleaner for instance).
- After launching it it will check your system to see if it is the good WUA for your system.
- If ok, then it will begin to download the upgrade - note that you can pause it, stop it, cancel it and when you launch again the WUA it will resume the download where it was !
- Then, when finished downloading upgrade, it will ask you t install it if you want to do it now.
- When you are ready, you start the upgrade installation.
Here again if any error, problem or what ever, you' ll need just to re start the installation (and not doanload again the upgrade).
- at this moment I encountered an error , it was telling me I had to unplug USB devices (keys, ssd) then installation completed.
After the upgrade succesfully installed, you still have WUA app and its directorie where there is still the upgrade files, and the famous windows.old in root C.
FOr me it is the best option to upgrade and if you want to cancel the upgrade like I did, I wen to recuperation on win settings and in less than 2 minutes all was back ; with still WUA app directorie & upgrade, meaning if you want to re upgrade you wont need to download it again
