Open an Administrative command prompt and switch to the Universal Agent for Windows user mode installation directory.
 
Execute the ubrsvc script and pass it the -remove option.
 
For example, assuming the Agent was installed to C:\Users\DAN~1.MOR\AppData\Local\Temp\universal, issue the following commands
 

cd C:\Users\DAN~1.MOR\AppData\Local\Temp\universal
ubrsvc -remove

 
The -remove option will stop the Universal Broker, delete it from the Windows Service Control Manager, and remove its message source registration with the Application event log viewer.
