If you don’t want Windows 10 installed automatically on Tuesday 9th February (or shortly after) then you need to take action now. I have this from two very reliable sources.

*This applies to Windows 7, Windows 8, and Windows 8.1. If you have these versions then Microsoft will “upgrade” you to Windows 10 as part of Windows Automatic Updates starting this Tuesday 9th February.
Some software (programs and apps) and hardware (printers and other things you plug in to your computer) will not work with Windows 10.
I can block this unwanted upgrade and turn off all the annoying popups about the upgrade.
I expect to be busy with this fix. I may not be able to reply to emails until after the deadline.
So, if you don’t want Windows 10 then phone me as soon as possible and leave a message if I am not available so I can get back to you.
