The end-user license agreement (BUM) is the contract between the software provider and the end user. This agreement grants the user the license to use the program under the terms set by the agreement itself. Another case is that of Apple, which has launched a legal battle against Psystar, which claims to have sold computers with Mac OS X preinstalled to violate the JLA and Apple copyright. He sued Apple for abuse of dominance, claiming that the current Macintoshes were common rcs and demanded that the ”exemption” of Mac OS X be implemented in a registered seat.  . The software manufacturer reserves the ”rights” on the software it creates and does not sell the software to the user, but the ”license” for the use of the software. The Florence justice of the peace ruled that she should order HP Italia to reimburse the operating system`s licence fee, plus incidental costs, to a buyer who did not plan to use the Windows operating system preinstalled on his laptop. The reason for the buyer`s complaint was that if the ENGINE was refused due to the operating system, HP provided only for the full return of the machine by the user and only the reimbursement of the acquisition cost without incidental costs. The judge found that the software was not an integral part of the purchased machine, which was due to the fact that it had a separate contract with very specific conditions and would not be available until after the purchase of the purchase.
As a result, the PC manufacturer`s full return procedure has been invalidated. It also considered that the applicable conditions, which expressly provided for a refund in the event of non-acceptance, were binding on the producer. The user`s inability to read the terms of the license agreement prior to the purchase of the software exposes this contractual system to discussions and controversies about the validity of its terms, how to accept it and how to return and refund it. It should also be remembered that, since it is a contract, the BLU may contain abusive clauses, which are therefore legally non-binding. To distinguish between them, it can be referred to the existence of specific laws or judgments that support or not the provisions imposed by the various clauses. The contract is presented to the user either as a sheet in the program distribution package or electronically during the program installation phases. In the case of the PAPER ECJ, acceptance of its terms and conditions is normally provided for in the perspective, unless the return of the product is made within a specified time frame defined by the contract itself. In the case of CLUE in electronic form, acceptance is made by clicking the corresponding button, followed by the installation of the program. Non-acceptance implies the impossibility of installing the program. The problem has become more important thanks to the spread of OEM software (original equipment manufacturers) on the personal computers of other manufacturers.
The availability of alternative software that can meet the user`s needs and is at a low or zero price means that a user has preferred solutions over those preinstalled on the PC. The user can therefore continue not to accept the CLA, which is related to the preinstalled product, and activate the refund procedure. Frequent short phrases: 1-400, 401-800, 801-1200, Another feature of EULA is that the purchase of the software program before the possible reading of the contract and its acceptance by the user.
