We are currently running a system upgrade to improve your overall experience.
Trend Micro Community will be back online on Saturday, October 19.
In the meantime, you can contact Technical Support here: https://esupport.trendmicro.com/en-us/home/pages/technical-support/contact/home.aspx
See you soon!
We understand that you want to know if Trend Micro changed your operating system to Windows 7.
For more details about your operating system, please contact Microsoft. They have more knowledge regarding that issue because we do not change, upgrade or downgrade any operating system. If you have questions regarding your Trend Micro product, we'll be happy to assist you.
