As of the 14th Jan 2020 Microsoft as no longer supporting Windows 7 so if you want to keep your computer secure you will have to upgrade to Windows 10
Even if you ditched Windows 7 years ago, you could still be affected by the Windows 7 End of Life. Any company that holds your data, such as doctor’s surgeries, for example, and still use Windows 7 could be putting your privacy at risk if they don’t upgrade.
However, Windows 7’s End of Life is no need for panic, either. PCs running Windows 7 won’t instantly stop working, nor should they become security risks overnight.
