Thêm chi tiết về những hạn chế

Chúng tôi muốn giữ lại trang về những "hạn chế của giấy phép" ngắn gọn, vậy chúng tôi đã di chuyển nhiều loại hạn chế của giấy phép đến đây. Sau đây là những phần văn bản đã in nhỏ trong các giấy phép sử dụng phần mềm của Microsoft.

  • Không rõ là ai có quyền dùng, nhận hoặc mua phần mềm của Hãng.

    Bản giấy phép sử dụng rất không rõ về vấn đề ai có quyền dùng, hoặc không dùng phiên bản của Windows hoặc của Office đang dùng. Có nhiều đoạn văn trong giấy phép sử dụng phần mềm Microsoft Office đang gởi ý rằng sẽ không cho phép một người láng giềng được viết một bức thư với Word trên máy tính của mình.

    It is however clear in the Microsoft Windows license that you may only give or sell your copy of Windows software to anyone if you are the first buyer. This means, that if you buy it from the user who initially purchased it from Microsoft, then you are not able to sell or give the software away to yet another user, even if you do not use it anymore, even if you buy the latest software version with your new computer.

  • You may not lease, lend or provide commercial hosting services with the software

    You cannot let professional users use your software, whether they pay for the service or not, and whether you use a "Professional" license or not.

  • The upgrade is only valid for the first license you use it on

    If that original license expires (for example because the computer it came on stops working), so does the upgrade. If you purchase an upgrade, you are not allowed to use the original software version anymore.

  • Educational versions are crippled

    If Microsoft accepts to define you as a student or an academic, you are allowed to buy an academic license, and install the software on three computers. But it is illegal to use it for any commercial purpose "or in any way related to the operation of any business enterprise or revenue-generating activities".

  • The components of the software may not be separated

    It is illegal to buy Microsoft Office, then install only Word on one computer, and only Excel on another. The Office suite is one single product.

  • Private information is collected

    The licence explicitly states that "Microsoft and its affiliates" collect technical information gathered on your computer by the software. They "may use this information solely to improve products or to provide customized services or technologies".

    In order to activate most Microsoft products, as part of the license agreement, your computer connects to the Microsoft servers and sends "technical" information. It can "solely" be used for pretty much anything.
