On the second Tuesday of each month, Microsoft releases updates for Windows and other products like Office through Windows Update (WU), Microsoft Update (MU), and Windows Server Update Services (WSUS). This is often referred to as “Update Tuesday” or “Patch Tuesday”. Microsoft delivers most of the security updates via this process to most of its products including Windows, Office, Internet Explorer and other. Since Microsoft has officially ended the support for Windows XP last month, they highlighted today that last month’s Update Tuesday on April 8th is the last “Update Tuesday” and Windows XP is no longer receiving updates.
So what does this mean if you’re still running Windows XP (click here to see if you are running Windows XP if you are not sure)? With today’s Update Tuesday, if you are still on Windows XP you will not receive any security or non-security updates through Windows Update or Microsoft Update. Because support has ended for Windows XP, we are no longer releasing updates to the general public for Windows XP going forward. If you continue to use Windows XP without support, your computer will still likely work but will become vulnerable to security risks and over time its performance will be affected.
Microsoft also pointed out that for specific cases in which some enterprise customers have custom support agreements with Microsoft, they will temporarily receive security updates for Windows XP to help bridge the gap during their migration process to a more modern operating system like Windows 8.1.
