Windows Defender is an anti-spyware program while Trend Micro is an anti-virus. There should be no conflicts with them running together.
As a general rule most anti-spyware programs like Malwarebytes' Anti-Malware, SuperAntispyware, Spybot S&D, Ad-Aware, etc will not conflict with each other or your anti-virus if using them as stand-alone scanners. However, if using any of their real-time resident shields (TeaTimer, Ad-Watch, Spyware Terminator Shields, etc) together at the same time, there can be conflicts when each application tries to compete for resources and exclusive rights to perform an action or function. Additionally, they may even provide redundant alerts which can be annoying.
