Just a quick question to ask if any1 knows what these actually do? I had a look my startup file to see what actually runs when the computer is turned on, but im unsure on what a few of them actually do and if i really need them.

If any1 knows what any of the following do, please tell !!!

sistray - C:\WINDOWS\System32\sistray.exe

khooker - C:\WINDOWS\System32\khooker.exe

pctspk - pctspk.exe

status - C:\Program Files\Internet Explorer\Connection Wizard\status.exe

tfswctrl - C:\WINDOWS\System32\dla\tfswctrl.exe

WinsysRsr - C:\Program Files\Wsr\WinsysRsr.exe

bpinstall - C:\Windows\bpinstall.exe /s
