Microsoft will end support for the original release version of Windows 10 — version 1507 — on May 9. The move, which is part of Microsoft's shift to its Windows as a Service (WaaS) model, was originally due to occur on March 26. However, Microsoft opted to push that date back and has now announced May 9 (via Windows IT Pro) as the end of service date.
If you're running Windows 10 version 1507, Microsoft says that you will no longer receive security and quality updates after the May 9 deadline. The solution is to update to the latest version of Windows 10. While you can still continue to use version 1507 on your computer, you'll open yourself to viruses and other security problems due to a lack of updates.
As for why Microsoft is ending support now, it explains:
With Windows 10, we introduced a new model whereby we release feature updates a few times a year, rather than holding back features for a new release every 2-3 years as in the past. In doing so, it's important that our customers stay current by installing feature updates as they are released.
As per Microsoft's recommendation, you can update to the latest version of Windows 10 by heading to its software download page and clicking "Update now." That will download the Update Assistant, which will help you grab the latest Creators Update release. And if you're unsure of which version of Windows you're running, you can check by typing "winver" into your taskbar search to open the About Windows box. If your current version is listed as 10.0, you'll want to update.
