If your computer is one of the few that still runs Windows Vista, be advised that on April 11th, 2017 Microsoft will stop supporting that OS altogether. People still using Vista need to know that if security flaws or problems are found in that OS after April 11th, Microsoft won’t fix them.
The April 11th deadline isn’t a killswitch for Vista. The OS will continue to run. Your Vista powered computer simply won't receive security updates and fixes after that date.
Given that Microsoft itself is refusing to further update their operating system, is hanging on to Vista worth the risk any longer? If not, you’ll want to install an up to date operating system in its place, either the latest Windows 10 or a cutting edge Linux distro such as
Linux Mint 18.xBest of luck as you move on from Vista..
