Windows 7 was officially overTime: Jan. 18, 2020
Support for Windows 7 is now officially over, which means Microsoft wants holdouts to upgrade to Windows 10 to keep devices running securely and smoothly.
If you have an older PC or laptop still running Windows 7, you can purchase the Windows 10 Home operating system on Microsoft's website for $139. But you don't necessarily have to shell out the cash: A free upgrade offer from Microsoft that technically ended in 2016 still works.
When Windows 10 was first released in July 2015, Microsoft offered an unprecedented free upgrade offer for Windows 7, 8 and 8.1 users, good through July 2016. But in 2017 the free upgrade tool was still functional.
I tried it out in November 2019, and was able to upgrade a 2014 Dell OptiPlex 9020 desktop from Windows 7 Pro to Windows 10 Pro. As of January 2020, readers are still emailing me and commenting below, saying that it's worked for them as well.
