Microsoft has warned Windows 7 users that support will end soon and on January 14, 2020, that support is officially stopped. However, even though it has been running for more than a decade, data from Netmarketshare (as of January 2020) revealed that around 26% of PCs still run the "old" OS.
Not surprisingly, many are hesitant to move to Windows 10. This is because of the bad reputation Windows 8 brings and also the hardware requirements that are also quite high for Windows 10. Even so, continuing to use Windows 7 means there will be no more patches and security updates. This runs the risk of an open computer to be exploited and attacked.
