Summary

This update improves the supportability of SQL Server 2012 and 2014 by adding information about whether Database Instant File Initalization is enabled for the instance. Database Instant File Initalization is enabled when the SQL Server service startup account is granted SE_MANAGE_VOLUME_NAME. Members of the Windows Administrator group have this permission and can grant it to other users by adding them to the Perform Volume Maintenance Tasks security policy.

More Information

This update is included in the following service packs for SQL Server:

Service pack 3 for SQL Server 2014

Service Pack 4 for SQL Server 2012

Service packs are cumulative. Each new service pack contains all the fixes that are in previous service packs, together with any new fixes. Our recommendation is to apply the latest service pack and the latest cumulative update for that service pack. You do not have to install a previous service pack before you install the latest service pack. Use Table 1 in the following article for finding more information about the latest service pack and latest cumulative update.
