1) There is a trial period which allows to evaluate the software for its fitness. The software is time-limited instead of function-limited, which means that it'll be in the consumer's fault if they bought the software and found out that it didn't work (except for very limited problems, for example relating to said registration step).
2) EU regulations do have a nuance - and in this case, 1) makes determination if said software needs to have a refund policy for the consumer harder. While WinRAR does have a refund policy, it seems the period for refunds is shorter than what is mandated. win.rar GmbH is based in Germany, so how it did bypass these rules? Spoiler: they didn't, the rules allowed them precisely due to the evaluation period.
