The small print in the contract

[AlanOstaszewski]

Did you know, that...

• Windows and Office are licensed, not sold.
  No one can buy Windows or Microsoft Office: instead users purchase a permission to use them. The license describes the terms of this permission. It is the restrictive legal text you have to click "OK" to upon install.
• An OEM-distributed software cannot be transferred to another computer.
  If you bought your computer with Windows or Office pre-installed (the so-called OEM licenses, or the "shrink wrap" Windows discs), if you change computers you must buy software again. The license is linked to one computer, and expires when the computer dies. It is then illegal to transfer the software on another computer.

You must abandon many rights to use the software.
1. Private information is collected
2. 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.)
3. You may not lease, lend or provide commercial hosting services with the software
4. And, and, and...

Its always stated, licensing, volume licensing etc. All software is like that, we just get the license to use it, we cannot change it nor can we sell it to others.
