So, there is no desktop icon or on any program you execute?
You can try this registry hack:
Go to Start > Run, and type regedit and hit Enter. navigate to the HKEY_CURRENT_USER branch, then expand Control panel, then click on the Desktop key. locate FeedbacktoolEnabled, right-click and choose modify and change the value to 3.
If that doesn't work, change the value to 1.
You may have to restart for it to take effect.
