SQL Server Express 2012 process takes a lot of memory

I'm using SQL Server Express 2012 on Windows8. Looking at the memory usage of SQL Server Express service in Task Manager I see:
Before running SSMS: 10 MB.
During SSMS usage: 35 MB.
(Long) after closing SSMS: 154 MB! the process is stuck in memory, and remains like that until I end it manually or restart Windows.
Is this behaviour normal? Is there anyhing I can tune in SQL Server so that the process won't stuck in memory?

Are you referring to the memory usage for SSMS.exe or SQLServr.exe?

If SQLServr.exe, this is because when SQL Server uses memory it does not release it unless restarted.

Not the SSMS itself, but the SQL service. Watch this picture - now it's gone up to 210 MB (don't mind the hebrew words and RTL task manager):my task manager right now

In SSMS right click on the instance, goto the memory tab and change the max memory to 50mb. This should release a significant amount of memory. If you need to use more just change it back.

Either that or just stop the SQL Server service when you are not using it...

Is changing the max memory to 50mb going to reduce anything from the good function of SQL server? What are the consequences of such change?

Yes, but if you change it back afterwards this is fine. It just allows you to release the used memory.

You didnt need to close SSMS. If you stop and start the sql server service do you get the same error?

What if you just try to open a new query instead of using the Object Explorer section? Or maybe trying an osql connection from the command line?

Also do you have any other services configured to use this SQL server? The other option might be to start it up in single user mode...

A restart did the thing. Thanks anyway.

Phew, thought I had broken your instance for a minute there... Probably best to raise the max memory a little though.

Did the reduction in max memory size have the desired result though?

Even after the reduction the memory usage of the process remained high as in the beginning. I'll leave it like that.

Unfortunately this is just how SQL Server operates. It is a service after all rather than a development tool like SSMS or Visual Studio.
