Windows Update Standalone Installer.
Syntax WUSA options Options: /extract Extract the package contents to a destination folder. This option was removed from Windows 10 due to a security issue, privilege elevation would allow executables to be extracted to C:\windows\system32 [x]. /kb uninstall a package led by using its KB number. Use only together with /uninstall. /quiet Run Wusa.exe in quiet mode without user interaction. When the tool runs in quiet mode, it runs without user interaction. The computer restarts if this is required. For example, if the Windows6.0-KB934307-x86.msu file is in the D:\934307 folder, type the following command at a command prompt to install the update package without user interaction: wusa.exe d:\934307\Windows6.0-KB934307-x86.msu /quiet When you use this switch, the Microsoft Software License Terms do not appear. /norestart Prevent Wusa.exe from restarting the computer. The /norestart switch is ignored if the /quiet switch is not present. If you run Wusa.exe together with these two switches, you must manually restart the operating system after the installation is complete (if the installation requires a restart) For example, if the Windows6.0-KB934307-x86.msu file is in the D:\934307 folder, type the following command to install the update package: wusa.exe D:\934307\Windows6.0-KB934307-x86.msu /quiet /norestart /warnrestart When this switch is combined with the /quiet switch, Wusa.exe prompts you before it begins a restart for install and uninstall operations. /forcerestart When this switch is combined with the /quiet switch, Wusa.exe forcibly closes applications and then begins a restart. /?, /h, /help View help.
