Must I give out the value of the pirated copies of Windows and Office that I used, knowing that they were pirated and that it was difficult to buy the original copies at the time? If so, should I pay it to the company or give it as charity?

It is absolutely impermissible to use pirated software. The user of such software must guarantee the value of the benefits lost by its owners and the damages incurred by them, and pay this value to the rightful owner. If that is not possible, then he should give it away as charity.
