Windows cannot find file

[moorpipe]

Why does Windows raise the following error "Windows cannot find 'c:\windows\system32\msconfig.exe'. Make sure that you typed the name correctly, and then try again.", if I try to run this program from its orginal location. But when I copy the exe file to another location no problems occur, e.g.
run "d:\desktop\msconfig.exe" "" "" "" 0x10000

Thanks in advance.
