Ever start up SSMS (SQL Server Management Studio) and not have your tabs for each new query window? Don’t panic, it is an easy fix.

1. Go to Tools. In that drop down menu click on Options.
2. In your options window you will want to expand the plus sign next to Environment if it is not already expanded.
3. Select General.  Please note, this should be the same as just selecting Environment, but I’m just going the long route.
4. Now you should see some options on the right side of the option window.  Look under Environment Layout.  You will see two options.
5. Select Tabbed documents.
6. Click the OK button.

Now your tabs have been restored.  Of course to remove tabs just select the MDI environment instead of Tabbed documents.
