I'm on Vista Ultimate and I've just noticed I have about 30-40 taskeng.exe
processes in the Processes list in Task Manager!

Restarting doesn't remove them, yet the PC seems stable and normal. Why are
there so many and how can I fix this? It's making my total processes to 124!
I have no viruses or spyware. The majority of the taskeng.exe processes are
around "896 K" in size.
