WSUS SUSDB Maintenance (Reindex + Update Stats)

Keep SUSDB fast: rebuild/reorganize fragmented indexes, then run sp_updatestats. Run off-hours; back up first.

Requirements

• Admin on the WSUS server.
• Either SqlServer PowerShell module (Install-Module SqlServer) or sqlcmd tools.
• WID instance uses the named pipe: np:\\.\pipe\MICROSOFT##WID\tsql\query.

Quick start

1. Save the SQL script as: C:\Scripts\WSUSDBMaintenance.sql (same as in this repo/article).
2. Run one of the following:

# PowerShell (SqlServer module) — SQL Server instance
Invoke-Sqlcmd -ServerInstance 'localhost' -Database 'SUSDB' `
  -InputFile C:\Scripts\WSUSDBMaintenance.sql -AbortOnError

# PowerShell (SqlServer module) — WID (local only)
Invoke-Sqlcmd -ServerInstance 'np:\\.\pipe\MICROSOFT##WID\tsql\query' `
  -Database 'SUSDB' -InputFile C:\Scripts\WSUSDBMaintenance.sql -AbortOnError

# sqlcmd CLI — SQL Server
sqlcmd -S localhost -d SUSDB -i C:\Scripts\WSUSDBMaintenance.sql -b

# sqlcmd CLI — WID (local only)
sqlcmd -S np:\\.\pipe\MICROSOFT##WID\tsql\query -d SUSDB -i C:\Scripts\WSUSDBMaintenance.sql -b
