Will your Windows 8.1 be supported? Will you be able to get the most current security patches, bug fixes, and new features? Windows Vista, Windows 7, and Windows 8 are all supported and will continue to be supported. However if you are not running the most current version of Windows 8.1, then your Windows will no longer be supported as of June 10th for personal users and August 12th for business users .
That sounds scarier than it is. Microsoft released an update in April for Windows 8.1. This update is going to be their base line for future updates. If your Windows Updates are set to run and apply automatically, then you are in good shape. If you prefer to manually run Windows Updates, then you may not be in good shape.
If you are sitting there and wondering to yourself, am I up to date? Simply go to the Start screen and look for the search button (the magnifying glass) in the top right corner. If it is there, then you are running the current version and are ok. If the search button isn’t there, then you will need to go to Windows Updates and run the update. The specific update that you need is labeled KB 2919355. Once that update is run and install, then your Windows 8.1 will be current and will stay support come June 10.
