NTI CD-ROM Filter Driver is the service name of the process called ntidrvr.sys, a type of driver file, and is a part of program Upper Class Filter Driver, which is created by NewTech Infosystems Inc. During the installation process of the software product Upper Class Filter Driver, the ntidrvr.sys is added onto the computer system, where it is registered into the Windows registry, stored on a folder location, and automatically runs in the background as a service of the program that houses it. In addition to that, this process is a Windows module, which suggests that it works with most or all versions of Microsoft Windows Operating Systems, or Windows OS, which include Windows 8, Windows 7, Windows XP, Windows Vista, Windows Server 2003, Windows 2000, Windows NT, and Windows ME. But despite the Windows OS used, ntidrvr.sys needs to remain active and running in the background, and the only time to terminate it is if it is causing problems that affect the performance of the system.
