post system() command on vista

ekw (1)
Hello, ive searched many times and i cannot find a solution to my issue.
Im creating a program that starts on startup, launching programs after x seconds.
But i have an issue when i use system()
1
2
 
      system ("C:\\PROGRA~1\\vistaa~1\\val.exe"); //Works ok
      system ("C:\\PROGRA~1\\windows sidebar\\sidebar.exe"); //Fails to work


when i dont use shortnames,

  
      system("C:\\program files\\...")


i get an error message C:\PROGRAM' is not recognized as an internal or external command, operable program or batch file.

i cant use the shortname for windows sidebar because there are 8 other's that begin with window, and window~8 doesnt work goes up to ~4

any solution other than renaming things or launching shortcuts?
Thanks for the help!

you could try:
system("\"C:\\program files\\...\"")

ie put \" at each end of your string.

i think you need to escape the spaces. ie
system("C:\\program files\\...")
becomes
system("C:\\program\ files\\...")

Grey Wolf's suggestion should work. I don't think escaped spaces shouldn't work in Windows because of the fact that '\' is the directory separator in Windows, and using the single '\' like that in C makes it think it is an escape sequence, which it isn't. In fact, gcc prints a warning when I use
system("dir C:\\Program\ Files");

Output:
test.c:5:10: warning: unknown escape sequence: '\040'

040 is the octal representation of the decimal number 32, which corresponds to the space character. Obviously that means it won't work either.

Grey Wolf's suggestion works though:
system("dir \"C:\\Program Files\"");

Output:
