Julie's mom uses Windows 7, but she wants to know if it's secure to do her online banking. Leo says that Windows 7 is at the end of life, which means Microsoft isn't fixing any bugs or exploits anymore. So if you go online, you run the risk of being hacked or infected. However, if you only use it for one thing, like online banking, it may be secure. That means no surfing to other sites, no emails, just going to the bank. If that isn't practical, Julie's mom can always upgrade to Windows 10 (it's still free). Download the Windows 10 Media Creation Tool and upgrade. It'll look about the same as Windows 7. But Leo also recommends just getting a new computer, like a Chromebook or iPad. Both are much easier to use for the average person and are very secure.
