Recently I installed Windows Desktop Search 4.0 because Windows Updates advertised with it. It comes with a nice list of improvements:
- Bug fixes - most of the reported bugs seen since Windows Vista RTM have been fixed.
- Rollback Recovery - your search index will roll back to the last known good state if an error occurs instead of being rebuilt from scratch.
- Windows software updates for Watson errors
- Faster previewer updates for Windows XP
- Improved performance when indexing Exchange in online mode - less packets and less RPC calls are made, which means less load on the server. Plus, no local cache (.ost)
- Support for indexing online delegate mailboxes
- Support for Group Policy settings (Search.adm/Search.admx) has been extended and improved, including per-user policies.
- An add-in for indexing redirected "My Documents" files (32-bit)
However, this version integrates the same way in Explorer as previous version. It replaces the 'Search' pane of Windows Explorer. Follow the steps below to fix this:
- Start Registry Editor by running regedit.exe;
- Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows Desktop Search\DS;
- Set ShowStartSearchBand to 0
You don't have to reboot. It applies immediately.
Hope this helps
