InstallShield is one of the most common packages employed by software makers to allow their products to be installed easily on their customers' PCs. The Update Service runs in the background and periodically queries the InstallShield website for product updates. Since InstallShield is so widely used, it can be installed on the system by many different programs. Also see: isuspm.exe.
