After April 11, 2017, Microsoft is ending support for the Windows Vista operating system. After this date, this product will no longer receive:
- Security updates,
- Non-security hotfixes,
- Free or paid assisted support options, or
- Online technical content updates from Microsoft.
Computers running the Windows Vista operating system will continue to work even after support ends. However, using unsupported software may increase the risks of viruses and other security threats.
======================================================
Remark: Due to negative reviews and extreme LACK of popularity, there are relatively few Vista users still remaining (percentagewise).
