Removing brackets from a text file

[teognost]

I have a text file like :
--ApplyTo:[Upgrade]
bla bla
--ApplyTo:[BusinessData]
IF NOT EXISTS(SELECT * FROM syscolumns WHERE id = OBJECT_ID('[og].[ClearVisionExport]') AND name = 'UserComment')
ALTER TABLE [og].[ClearVisionExport]
ADD [UserComment] [VARCHAR] (4000) NULL
--ApplyTo:[None]
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS ON

I need to remove all the brackets after ApplyTo so :
ApplyTo:[Upgrade] becomes ApplyTo:Upgrade
ApplyTo:[BusinessData] becomes ApplyTo:BusinessData
and so on.
I tried to implement a replace step(see the attachment) but I cannot make it working.
Any idea how to do this?

The expression

ApplyTo:[[(\w+)]]

should be

ApplyTo:\[[(\w+)\]]

(square bracket characters have special meaning in regexes too and must be escaped to be treated as literals by the regex engine).

I see,thanks for info!
And what about the other part -from 'Text or regular expressions to replace matches with'?What should be there in order to have the item inside the brackets found previously?
Basically I need to have something like :
ApplyTo:ITEMINSIDEBRACKETS
but I do not know how to put it.
I looked in help but I still do not understand...

$1 or \1. Your sample worked in my tests after modifying as above and checking the Replace in File step (to include in the build).
