It will open the system restore window the option that will be checked by default will be restore computer to an earlier date. Click on next, from the calendar select a date in bold earlier then the day you uninstalled that program. And just click next and proceed further with the system restore. Note system restore only reverts the changes you have made to your system it wont delete any data.
