If your computer is running Windows, you may be eligible for a free upgrade to Windows 10, Microsoft's newest operating system. The free software is available to most users whose computers are currently running Windows 8 or Windows 7.

Like any upgrade, there are benefits and pitfalls of adopting a new operating system. Before you take the plunge, you may want to attend a free seminar that is especially aimed at adults 50 and older.

The Windows 10 seminar will show you all the new features of the new operating system, but perhaps most important, it will give you tips on how to upgrade so you don't lose any of your data and programs.

The seminar is Wednesday, Sept. 30, 4-5:30 p.m. at Northport Library. For more information, call 631-261-6930.
