On January 14th 2020 Microsoft will remove Windows 7 from support and it will no longer receive critical updates. The primary reason is that Microsoft have shifted to improvements for Windows 10, which is faster, more secure, and becoming more cross compatible as updates are rolled out.
As an operating system gets older it presents more security threats as people have gotten to know the ins and outs of its features. And with its abandonment these security threats will no longer be checked or patched by Microsoft. This includes all versions of Windows 7 (Starter, Home Basic, Home Premium, Professional, Enterprise and Ultimate).
Drivers will no longer support Windows 7 builds and hardware may not be recognised. If you’re looking to put the latest GPU into your Windows 7 machine in the near future you may find that the driver version is out of date and much of the software you’re running cannot recognise the card. For example: Redshift requires the latest Nvidia drivers in order to render.
Unfortunately, if you haven’t upgraded to Windows 10 by now then you’ll need to pay for a license as the free upgrade ended in 2016.
Microsoft are, however, offering paid for extended support for an as yet undisclosed amount.
