How to change the destination file for Windows Updates is a particular problem that arises for some people. Windows Update is a service by Microsoft that allows systems to either manually or automatically download updates for their operating system. It is mainly useful for downloading critical updates and other security fields. In the default, the operating system will create temporary files in which to store the updates before they are installed. For some users, this is not ideal and would prefer to change the destination that the windows update files are stored in.
The main destination file for windows update is usually C:\windows\msdownload.tmp as the download folder. In versions of Vistas, it can be accessed by visiting the folder C:\windows\softwaredistribution\download. The files in XP will be stored with the prefix $Nt in front and have been compressed. These update files are stored in a temporary folder in case there is a problem with downloading. It is possible to change the destination file by allowing all updates to be installed into one folder for easy removal.
