Warriors face up to the challenge of a dangerous Brive side - who had lost only one game in 16 in all competitions before last weekend - at Sixways Stadium on Saturday (kick-off 1pm).
Assistant forwards coach Windo believes the 'shackles will be off' Warriors after they defeated Saracens last weekend to secure Guinness Premiership status.
However, he warned that a star-studded Brive team, that is set to include England stars Andy Goode, Ben Cohen and Steve Thompson, will prove difficult opposition.
"It's nice to secure our safety with a few games to go. It alleviates the pressure and releases the shackles with the cloud hanging over us. That little bit of pressure has now gone," said Windo.
"But Brive are a very good side, we have been doing our homework on them. They play like a typical French side with flair but also a big set of forwards. They are well coached and well drilled; it will be difficult for us.
"There is a notion that French sides do not travel well, but Brive will not suffer that and we expect a tough afternoon. You don't become a top five side in France without being a good side and they have been on a good run of form.
"One player to watch is Andy Goode, who is one of the best fly halves for England at the moment. He has a good kicking game and it is no surprise to me that he is part of the England set-up at the moment, we will need to watch him."
Windo revealed Warriors would be putting out a strong side for the cup clash and a number of players who have missed recent weeks could return.
"We will be putting out the strongest side that we can. We are hopeful that Rico Gear will be available for us to call upon again and James Collins is also back in training," added Windo.
"It is a great competition and a big day for the club and the supporters to get to a cup final. Last year was a great occasion and we will be going all out for a win against Brive to get back there.
"The Heineken Cup is the prize at the end and if we get there we will make ourselves ready for that challenge."
