Like Windows XP in it's day, Windows 7 is still probably the world's favourite Microsoft operating system with a 20.04% share of windows desktop operating systems.
Mainstream support for Windows 7 ended on 13th January 2015 but extended support ended on 14th January 2020 as detailed in The Microsoft Support Lifecycle page.
We like Windows 7 and consider it a good all round operating system which is good for both business and home use. For those that have used Windows XP and Vista it is a logical progression and is easy to use.
We would now recommend an upgrade to Windows 10 as detailed in the Windows 10 page.
