Are you still using Windows 7?
Support for Windows 7 is ending next week (14th January). Your machine will continue to work, however it will not receive any security patches which will leave you extremely vulnerable to cyber attacks.
Chances are, that if you are running Windows 7 then your machine is also running rather slow! Why not upgrade your hardware at the same time as software and get your machine running quicker than when you first bought it for a fraction of the cost of a new machine.
Get in touch now if you would like to hear about possible upgrading options.
