Vista to Windows 7 upgrade 喜忧参半

Vista to Windows 7 upgrade 喜忧参半，以下英文原文大致意思就是，2009年7月1日，凡是购买了预装VISTA除了basic版本以外的用户都可以免费升级到windows 7，也就是我的那个vista basic 版本就没希望了，郁闷。

For everyone wanting a free upgrade to Windows 7, Microsoft finally has an answer. Unfortunately, it probably isn’t the answer you wanted to hear.

Starting on July 1, 2009 any new systems purchased will be eligible for the no-charge update. In addition to purchasing the PC after that date, there are three more rules:
End users must purchase a new PC that is pre-installed with an eligible Windows Vista OS. Retail boxed Vista versions likely won’t qualify.
Your computer must have a valid Windows Vista COA attached.
The only Windows Vista® versions eligible for the program are Home Premium, Business, and Ultimate. Vista basic users are out of luck.
Oh yeah, there’s one more little detail that may be important:
Participation in the program is optional, so it’s ultimately up to the OEM that builds your system to allow the upgrade. In all fairness, this has been the case with every other Windows upgrade — and almost all vendors participate.

With news like this, I’d fully expect to see the Windows 7 beta torrent become even more popular.
