The Windows Vista end-user license agreement (EULA) is a 14-page PDF document. (The EULA for Windows XP Pro SP2, by contrast, looks to be only a couple of pages.)

This is probably the most concerning part of the EULA:

The software is licensed, not sold. This agreement only gives you some rights to use the software.

Oh, you thought you owned your copy of Vista? Nope. It belongs to Microsoft, along with your ability to access all of your client’s data (not the data itself, obviously).

Update: You can now pre-order you upgrade to Windows 7.
