A word of warning. I logged onto my PC & netbook this morning and found that Microsoft are trying to install Windows 10 automatically via Windows Update.

This has happened sometime in the last month.
If you open Windows Update via the Control Panel you are now being presented with the current screen instead of the number of items waiting to be installed:
If you then click on 'Show all available updates' and select 'Optional' you will then see the Windows 10 Update selected by default. In my view this does not make this optional.
If you hide the update then it automatically reappears in the Optional list the next time you open Windows Update!
I DON'T want to update to Windows 10 at the moment. I can see no point for me personally to upgrade to Win10, but if I did decide to do so I wouldn't do it until Easter of next year.
Why can't Microsoft let us make our own decisions as to when or whether we want to grade? Win10 offers me no benefits just lots of headaches from trying to teach my 91 year old father what the changes are and how they affect him.
