So, you have a folder with Windows Update Files (e.g. downloaded from Microsoft Update Center):
... WindowsXP-KB938464-v2-x86-RUS.exe WindowsXP-KB944043-v3-x86-RUS.exe WindowsXP-KB946648-x86-RUS.exe WindowsXP-KB950762-x86-RUS.exe WindowsXP-KB950974-x86-RUS.exe ... ... (a lot of files)
If you have such a folder, then it's logical to install all the files automatically at once, with a single command line.
