Prerequisites Installer - Online Documentation

/auto : Proceeds to an automated install, with options defined in the next command lines switches (all the switches below are mandatory for the automated install):

      - /site : Defines which Windows Update website to use by default in the Start Menu shortcut. Possible sites: V5, V6. Examples: /site:V5 or /site:V6

      - /mu : Sets if Microsoft Update will be enabled or not during the installation. Possible options: enabled, disabled. Examples: /mu:enabled or /mu:disabled

      - /provider : Sets the Update Provider to use when checking for updates. Possible options: LU, WUR. Examples: /provider:LU or /provider:WUR
         The Custom Update Provider is not supported in command line use.

      - /endmsg : Displays a message saying that the installation at the end has finished. This switch being missing will result in a simple program closing at the end of the installation.

      Example full command: wurv5patchertool.exe /auto /site:V6 /mu:enabled /provider:LU /endmsg

Logging
The Prerequisites Installer creates a log at the root of the system drive (in most cases, C:\). This log lists every action the installer performed, in order to help bug tracking. The log filename is WURPREREQINST.LOG.

Supported Operating Systems
The Prerequisites Installer supports the following operating systems:

• - Microsoft Windows 2000 (Professional, Server, Advanced Server);
• - Microsoft Windows XP (Home, Professional, AMD64);
• - Microsoft Windows Server 2003 (Standard, Enterprise, Datacenter, AMD64);
• - Microsoft Windows Home Server;
• - Microsoft Windows NT 5.0/5.1 based operating systems.

Warning!
This patch modifies some system files (WUPDMGR.EXE, WUWEB.DLL, MUWEB.DLL and WUAUENG.DLL). Please back up any important data (or make a snapshot in case you're using a virtual machine) before installing it on your computer. We do not believe anything should go wrong, but make sure everything is safe before running it.
The Windows Update Restored Prerequisites Installer cannot be uninstalled (any uninstallation will have to be done manually, or using Add/Remove Programs for the DLLs and WUPDMGR.EXE).

How does the Prerequisites Installer work?
The Prerequisites Installer works by only extracting the necessary resources to a temp directory (%temp%\WURPatcherTemp) and then installing/copying each file in its corresponding directory (mainly System32, System32\DLLcache and SysWOW64). It patches the entire operating system, as well as the Windows Update shortcut in the Start Menu.

We've made sure to use strong and efficient methods to prevent your operating system from being corrupted while patching it, but please report any bug you find to Windows Update Restored, so we can fix them for the next release.

With Legacy Update
Installing Legacy Update even though you've already used the Prerequisites Installer on the same computer shouldn't cause problems (the Prerequisites Installer even offers to the user the ability to use Legacy Update as Update Provider). Bare in mind that, if you chose to install Legacy Update and decide to uninstall it while still having this patch installed with Legacy Update selected as Update Provider, you might get errors when trying to run Windows Update Restored V5/V6, as the service will run on Legacy Update in that case.

Windows 2000 Users
The Prerequisites Installer supports all editions of Windows 2000 running Service Pack 3 or Service Pack 4.
Using version 1.5, Windows 2000 users may recieve one or more Windows File Protection warnings telling them that system files have been modified, and need to be replaced using the Windows 2000 CD-ROM. In order for the installation to take effect, please always click "Cancel" and "Yes" at each prompt you see, otherwise the patch won't work.
