Windows Task Manager is used to view details about processes running on your computer. Since it can be used to terminate programs that are misbehaving or are viruses disguised in the form of harmless programs, most spyware and viruses disable it to prevent themselves from being closed through it. Some administrators also disable Task Manager to prevent users from closing important security programs like antiviruses and anti-malwares.
Registry Editor is a useful utility in Windows which allows users to easily change advanced Windows settings by altering registry keys present in a hierarchical arrangement called the Windows Registry. Despite being such a powerful tool, Registry Editor is not totally error-proof.
