• 910219. how to download and keep the Windows Update files?

  Hello

  What is the ideal way to update Windows? now, Windows downloads the selected updates. where? I do not know! and after their installation, it removes the packages for installation on my computer. This causes the downloaded updates are lost, and I can't use them to similar machines that need to install the same updates. for these machines, I have to download updates again! This causes my internet to be charged again while it is not really necessary.

  the ideal way, in my view, is that I can specify a folder for the Windows Update service. It can use a default folder for that also. After selecting the updates, I want to install in my system, it checks to see if the update is already existing in the folder. only if NOT it downloads. then after downloading it maintains the package in the same folder after installing. installation should be done automatically as it is done now. Then I can move the folder to another machine. in the second machine, I also choose the update I want to be installed which are mostly the same as the first machine. for example, Windows Update only consumes my internet traffic for updates that are not yet downloaded. I wonder why Windows Update doesn't currently work the same way?

  by this method, I can at least use the consumption of traffic and I can access the latest updates with the easier and faster way. I I would like to choose a memory flash for this purpose and keep the folder inside.

  is there a way to achieve this?

• How to find out the Windows Update Agent version I am running

  Anyone know how I can find out which version of the Windows Update Agent I use?  I checked everything and no menu where only allows me to check the version.  This link http://support.microsoft.com/kb/949104 tell me how to get the latest version, but it is not to tell me how do I know if I am running on the latest version.
   
  And what makes it reset my of update windows components?  I read this link (http://support.microsoft.com/kb/971058#appliesto) and understand how to reset components, but I'm not clear on how this will affect my windows update.

  I have Windows Vista Home, SP2.

  Thank you very much!

  Ohanna Hello,

  Thank you for using the Microsoft answers Forums.

  Determine the current Version of WUA:

  Determine the version of Windows Update Agent (WUA) before using it. The current version of WUA is determined by the version of the c:\windows\system32\wuaueng.dll that runs in the current installation of Windows \System32 directory. If the c:\windows\system32\wuaueng.dll is version 5.4.3790.1000 or a later version, WUA is installed. A version earlier than 5.4.3790.1000 indicates that the Software Update Services (SUS) 1.0 is installed.

  When a call is made for SUS 1.0 using the API INTERFACE, an HRESULT of WU_E_AU_LEGACYSERVER is returned.

  You can also use the IWindowsUpdateAgentInfo::GetInfo method to retrieve the latest version of file of the c:\windows\system32\wuapi.dll that runs on a computer. The IWindowsUpdateAgentInfo interface is not supported in WUA 1.0.

  For more information, see update the Windows Update Agent.

  Thank you.

  UDAY $012 please let me know that whether the solution worked or not, I thank you and appreciate your comments.

  I understand you want to make a backup of windows 8 and reuse it again with another version of windows.

  Unfortunately the Windows updates cannot be saved nor can they be transferred from one computer to the other.

  After you perform a new installation, you must reinstall Windows updates again.
