Conime.exe (C:\WINDOWS\system32) is "Console Input Method Editor" which is used if you have more than one input language configured. Under Windows Vista it tends to multiply itself and take lots of CPU and memory resources. Microsoft refuses to fix this bug (or probably it's a feature?)

One method to get rid of this annoyance is to enable only one language (Control Panel – Regional and Language Options – Keyboard and Languages)

Another one is to remove/rename the binary:

takeown /f %windir%\system32\conime.exe
icacls %windir%\system32\conime.exe /grant %UserName%:F
rename %windir%\system32\conime.exe conime.bak
