The Windows Home Server team released a minor software update for the product as part of our ongoing customer- driven improvement program. Current users will receive this software via Windows Update, either on or shortly after the release date of November 25, 2008.

Below is a summary of what is included:

This update improves the interaction between home computers running Windows Vista and a Windows Home Server-based system when copying files or folders that are larger in size than the free space available on the first (or primary) hard drive to a Shared Folder.  Additionally, this update resolves certain issues which can happen when restoring files and folders from Windows Home Server, such as the opening of a Home Computer Backup sometimes stalling at 79% complete.  The update also improves the search functionality when using remote access.

The entire Windows Home Server team would thank the people that have used our Connect site to submit bugs with detailed logs and "repro" steps to help the team understand issues with the product that are not easy to reproduce.  The home server team has one of the oldest Connect sites dating back to October, 2005.  But most importantly we have the 4th most active site due to the fact that we keep it open so people can continue to submit product suggestions and bug reports that are directly reviewed by the product team.
