Database after restore process still display Restoring I restored Database from Backup File (in Management Studio) and after restore, Database showed Restoring, then I deleted files from disk (engine's stopped), then I tried Restore again with success, on both cases I leave Restore Process on Default Options

I have no idea why, dump file I created after restart of enviroment, without active Connection(s) 

my question: is possible somehow to stop the Restoring status, if is there some tools for that
By default, a DB is not ready to use. It stays "restoring" ready to receive log restores.

Simply run this to bring the DB on-line

RESTORE DATABASE MyDB WITH RECOVERY


Or using the GUI, this is step 12 in the MSDN SSMS "how to" (a different place to what you mention)
