I think xcopy uses suffixed optional forward-slash switch options, so it might be getting confused?
I'd try (note the 'r' prefixes for raw string literals):

    os.execl(r"C:\WINDOWS\system32\xcopy.exe", r"E:\MainWeb\dreampics\*.*", r"E:\MainWeb\dp")

I don't know what the length or count limits might be on expansion of "*.*" but hopefully
it it pretty big.
