WinRAR is one of the most popular file compression programs – many people have it on their computers and have been using it for years. Many people wrongly assume that WinRAR is free., because after installation it is available immediately and seems to work without any limitations. In fact, WinRAR is shareware – this means that it can be legally used for free only for a limited time (trial period 40 days).
After this period, the program continues to run and merely displays a reminder to register each time it's launched. This clever solution often causes users to reflexively close the message and continue working, unaware that formally, from the 41st day they use WinRAR in violation of the license and law.

WinRAR licensing policy (40-day trial)
The WinRAR license includes a 40-day trial period.During this time, you can use the program free of charge and fully legally to assess its usefulness. After 40 days, you must either purchase a license or uninstall the program.This is clearly indicated by a message displayed when the application is launched. Unfortunately, most users ignore this prompt, assuming that since the program is still running, nothing bad is happening.
It is worth emphasizing that WinRAR is not open source software or freeware – it is a commercial product. The price of a WinRAR license in Poland is approximately PLN 150–250, depending on the version and number of workstations. This isn't a huge amount compared to, for example, the prices of operating systems or office suites, but still few users decide to purchaseThe program often lingers on hard drives long after the trial expires.

Is it legal to use WinRAR without a license?
Short answer: no, using WinRAR after the trial period without paying for a license is illegal. This is equivalent to using an illegal, unauthorized copy of the software (piracy). The program manufacturer clearly states that further use after 40 days requires purchase – lack of a license means a violation of the terms of the license agreementIn practice after the mentioned 40 days we use WinRAR in a manner inconsistent with the law, even if the app technically still works.
You should be aware that by accepting the license agreement during installation, we undertake to comply with its terms. Continuing to use it without registration constitutes a violation of these terms. From the perspective of copyright and criminal law, this is treated as using the program without the consent of the rights holder, which falls under software piracy.

Legal consequences and examples
Using unlicensed software (including WinRAR) may have serious legal consequences. In Polish law unauthorized acquisition of a computer program in order to gain financial gain is a crime – Article 278 §2 of the Penal Code carries a penalty of up to 5 years in prison. Simply put, law enforcement agencies may treat continued use of WinRAR without a license as software theft.
In practice, however, the application of these provisions in the context of shareware is sometimes controversial. For a crime to be committed, it is necessary to demonstrate intentionality. – conscious, intentional use of an unlicensed program for profit. In the case of WinRAR, this can be difficult to prove, as the user may have, for example, forgotten about the program or been unaware that they were breaking the law (since they initially used it legally during the trial period). Polish courts have shown some understanding in such situations – there is a known case of Mragowawhere the court did not convict users of WinRAR and Total Commander of violating shareware licensesThe court found that using shareware after the trial period does not meet the criteria for the crime of misappropriation (there is no obvious theft with intent), although it does not exclude civil liability for violating license terms.
Note: Success in court for such individuals is the exception rather than the rule. It should not be assumed that punishment will always be avoided—another court might have assessed the case less leniently. Furthermore, even if the user avoids criminal liability, civil liability remains—the manufacturer may seek compensation for unpaid license fees.
In a corporate environment, the risk of detecting illegal WinRAR is high. Enterprises are subject to regular software legality checks. It happened that a company with legal Windows and Office was "caught" by illegal WinRAR installed on the diskIn the event of an audit or police raid, failure to obtain a license for even one program may result in severe financial penalties, the need to pay overdue license fees, and in extreme cases, criminal proceedings against the owners or IT administrators.
Also private individuals they are not completely safe – although home computers are rarely tested, there were cases of "hunting" against pirates (e.g., the high-profile case of the Lex Superior law firm, which reported masses of IP addresses suspected of piracy to the police.) When storing illegal programs on a disk, there is always a risk that they will be discovered in the event of any investigation (even for other reasons).
In summary, using WinRAR without a license exposes us to criminal and financial liability. In extreme cases, you may be held responsible for piracy (software theft), or in less severe cases, you may be required to pay compensation/licenses along with possible fines. It's not worth the risk.
Free WinRAR alternatives
The good news is that there are free programs that offer functionality similar to WinRAR, so you don't have to break the law or spend money. It's worth considering using them instead of pirated WinRAR. The most popular alternatives are:
• 7-Zip – A completely free and open-source archiver. Supports .zip, .rar (unzipping), and many other formats. 7-Zip is constantly updated and is considered the most popular alternativewhich will allow you to do everything that WinRAR does, without exposing yourself to legal problems. It has a simple interface and high compression efficiency (especially in its own .7z format).
• PeaZip – a free, open-source archiver that supports a variety of formats (including .rar). It has a user-friendly graphical interface and additional features (archive encryption, etc.).
• Built-in system tools Both Windows and macOS can natively unpack popular .zip archives. While they don't support the .rar format without additional software, for basic .zip file use, this may be sufficient.
• Other substitutes – there are also other free tools like Bandizip, Zipware Whether GNU Tar on Unix/Linux systems. If you just need to unpack a .rar file, even online applications can do it without installation (though you need to be careful about data security and privacy).
Attention: WinZip, often confused as an alternative, it's not free – it's also shareware (trial), so it doesn't solve the legal issue. If your goal is to use the archiver for free and legally, stick to freeware/open source programs like those listed above.

This article is not intended to scare you, but warn and make aware:
WinRAR is not freewareIf you are still using it after the trial period has expired and you have not purchased a license, you risk legal consequencesIn practice, many private individuals will never be punished for this, but entrepreneurs should absolutely not underestimate this – during an inspection, even such a seemingly trivial “pirate” as WinRAR can cause serious problems.
There are three most reasonable options: remove the program, purchase a license or switch to a free alternative. With excellent free tools like 7-Zip available on the market, there's really no need to take any risks. Using legal software gives us peace of mind—and we appreciate the creators, either buying their product, or choosing free solutions that legally meet our needs. Regardless of the choice, it's important to be an informed user and follow the law. At the end of the day It is better to prevent problems than to deal with their consequences.
