After April 11, 2017, Windows Vista customers will no longer receive new security updates, non-security hotfixes, free or paid assisted support options, or online technical content updates from Microsoft. Microsoft has provided support for Windows Vista for the past 10 years, but the time has come to invest resources towards more recent technologies.
What happens if I continue to use Windows Vista?
If you continue to use Windows Vista after support has ended, your computer will still work but it might become more vulnerable to security risks and viruses. Internet Explorer 9 is no longer supported, so if your Windows Vista PC is connected to the Internet and you use Internet Explorer 9 to surf the web, you might be exposing your PC to additional threats. Also, as more software and hardware manufacturers continue to optimize for more recent versions of Windows, you can expect to encounter more apps and devices that do not work with Windows Vista.
Microsoft has also stopped providing Microsoft Security Essentials for download on Windows Vista. If you already have Microsoft Security Essentials installed, you'll continue to receive antimalware signature updates for a limited time. However, please note that Microsoft Security Essentials (or any other antivirus software) will have limited effectiveness on PCs that do not have the latest security updates. This means that PCs running Windows Vista will not be secure and will still be at risk for virus and malware.
