In a Command Prompt window, you can start the SQL server in minimal configuration mode by typing:
sqlservr -c -f
This command also starts the SQL server in single-user mode. Also, the server will not run any startup stored procedures. Additionally, when you start the SQL server in minimum configuration mode, then SQL Server automatically sets the size of tempdb to 2 MB on its default device. You must then manually increase the size of tempdb as necessary.
