In Windows 8 or Windows Server 2012, the Windows Search Service may bloat the Windows.edb file. When this issue occurs, the Windows.edb file grows to a very large size and consumes lots of disk space. In some instances, the file size can be larger than 50 gigabytes (GB).


Update information

To resolve this issue, install update rollup 2836988 for Windows 8 and Windows Server 2012. For more information about how to obtain this update rollup package, click the following article number to view the article in the Microsoft Knowledge Base:
2836988 Windows 8 and Windows Server 2012 update rollup: May 2013

Note This update is preventative, but not corrective. To reduce the size of a Windows.edb file that is already affected by this issue, you must rebuild the search index after you install this update.
