Microsoft has formally announced Windows 7 End of Support. Because Microsoft no longer fixes issues on this version, it has become increasingly difficult for Trend Micro to keep users safe on this operating system. We encourage all of our users to upgrade their PCs to a more modern operating system which will provide greater stability and security.
