Support for Windows 7 ended on January 14th, 2020. As of writing, Windows 7 has missed 6 months worth of updates released to patch vulnerable code.

If you are still running Windows 7 you need to upgrade to a currently supported operating system sooner rather than later. Running unsupported software, especially an operating system, leaves your device open for malware and cyber criminals,

Many PCs running Windows 7 can easily be upgraded for free to Windows 10. You can find more information in an earlier post. The Microsoft website has the minimum requirements for hardware as:

• Processor: 1 gigahertz (GHz) or faster processor or SoC
• RAM: 1 gigabyte (GB) for 32-bit or 2 GB for 64-bit
• Hard disk space: 16 GB for 32-bit OS or 20 GB for 64-bit OS
• Graphics card: DirectX 9 or later with WDDM 1.0 driver
• Display: 800 x 600

This means that Windows 10 can be run on reasonably old hardware.

Another alternative would be to install a Linux distribution such a Ubuntu, or if your PC is very old, Lubuntu.
