It's impossible to not violate something in a EULA in the course of normal use. Software companies count on this. Many EULAs prohibit the use of software by a non-licensee (read: friends, family), so that "guest" account in Windows is a violation of the EULA. If you ever bother to read some of these very lengthy documents you would find them almost impossible to understand without a law degree. Lawyers, thanks again for ruining my day. Signed. US Citizen.
