We have a SQL 2012 Standard server running on Windows 2012 R2 Standard. Between 6 databases (production and test), the files add up to 76GB. However tempdb grew to 131GB. I ran shrink database from SQL Management Studio and the size decreased to 122GB but it will not shrink any more although available free space is 99%.
I have tried shrink database, shrink files, dbcc freeproccache. None of the database is in read-only mode.
What else can I do to shrink this or identify why it is large?
