  • FOR WINDOWS XP AND WINDOWS VISTA USERS: Microsoft has formally announced Windows XP (April 8, 2014) and Windows Vista (April 11, 2017) end of support. Because Microsoft no longer fixes issues on Windows XP and Windows Vista, it has become increasingly difficult for Trend Micro to keep users safe on these operating systems. We encourage all of our users to upgrade their PCs to a more modern operating system which will provide greater stability and security.
