consent.exe is legitimate Windows Vista User Account Control (UAC) process, which is important for preventing unauthorized changes to computers and keeping them safe. It guarantees that only trusted applications receive administrative privileges by prompting a user for permission when installing software or changing computer's settings. That's why we do not recommend terminating consent.exe. Typically, this file is located in C:\Windows\System32 folder and is launched once PC boots up. Sometimes consent.exe may be a cause of system's slow downs and high CPU consumption.
Malware creators like to use the names of legitimate files in order to prevent the removal of their viruses. So, be aware that consent.exe name may also be used to hide the presence of a virus. If your consent.exe is located not in the c:\windows or c:\windows\system32 folder, check the PC with updated anti-spyware to make sure that it is not a threat.
