Windows 10 (1803, 1809, 1909) Ending Support May 11, 2021
Are you still running Windows 10 (1803, 1809, 1909)? As of May 11, 2021 they will no longer be supported.
No longer supported means you will no longer receive updates like security patches. This leaves you at risk. Why? Because security patches fix vulnerabilities found in the operating system, and left unpatched, leave you at risk of being compromised.
Don’t think it matters? Well, it’s like keeping your front door of your house unlocked 24/7.
