Need a batch program to install all manually downloaded Windows Updates in one single click

From How to Install a .msu Update on Windows 7 from the Command Line:

To install an .msu update package, run Wusa.exe together with the full path of the file:

• If Windows6.0-KB934307-x86.msu is within D:\934307\, install the update package via:
  wusa d:\934307\Windows6.0-KB934307-x86.msu
  
  
• To run without user interaction, use the /quiet switch (auto-reboots if required).
  wusa d:\934307\Windows6.0-KB934307-x86.msu /quiet
  • When using this switch, Microsoft's Software License Terms do not appear.
  • To prevent an auto-reboot, use the /norestart switch, which is ignored if /quiet is not present (if installation requires a reboot, Windows must be manually rebooted):
    wusa D:\934307\Windows6.0-KB934307-x86.msu /quiet /norestart

Using this format, run the following batch file contents from within the folder containing the updates:

Set Folder="C:\updates"
for %%f in (%Folder%\*.msu) do (
  wusa.exe %%f /quiet /norestart
) 

Notes:

• You can check whether the .bat file worked or not by trying to manually install the update; Windows Update should reply Update already installed on this computer.
• If you see nothing works after running the batch file, delete /quiet to see the error report.
