I am using
Liferay 6.2 EE
Microsoft SQL Server Management Studio 2012

Here I am facing problem to first install and then login as a "sa" user.
So first install SQLEXPR_x64_ENU

I tried to search from windows + s

It is installed but not visible in search.
You have to search it by pressing windows button like

Once you select it then visible to search in windows 8.
First open
SQL SERVER configuration manager.
then in
Sql Server Network Configuration -> protocols for SQLEXPRESS

Enable all protocols

Please restart sql service.
By closing sql server management studio window or Sql Server Configuration Manager windows doesn't stop service.
For start and stop service windows + r (run command) write services.msc
and then can restart SQL Server (SQLEXPRESS).

Now open sql server management studio
After connect SQL Server using Windows Authentication mode
