My E1-570 has Windows 10 version 1809 loaded and works fine. Microsoft have downloaded automatically a version 1903 but when I checked with them before letting the download activate I was told that the laptop version was not compatible with the existing Bios.
The suggested I contacted Acer to find out if a change of Bios "could" be loaded onto the laptop so that the latest version (1903) would work.
I would be grateful for your input on this please.
Meanwhile I have used the following to stop any further uploads, it "may" help others in the same situation.
Select the Windows flag icon + R .
Type in box "Services.msc" then OK - Scroll down the resulting list of "cogs" until you see
"Windows Update" Now DOUBLE CLICK this item - (Opens "Windows Update Properties (Local Computer))
The GENERAL Tab should be visible.
Look for STARTUP TYPE (sub menu) and SELECT "Disabled" CLICK OK at foot of section =
