Alvin, I could not find Windows-10 User Account Control setting to "Never" (essentially Off). Where is it please.
I am sure Alvin won't mind me stepping in here.
To turn User Account Control (UAC) off in Windows 10:-
Type UAC in the search field on your taskbar.
If the search field isn't visible, right-click the Start button and choose Search.
Click Change User Account Control settings in the search results.
Then to turn UAC off, drag the slider down to Never notify and click OK.
You may have to confirm your selection or enter an administrator password.
Alternatively, via Control Panel, see attachments below.
Reboot your PC for the change to take effect.
