Windows 7 was released as a public beta in its build 7000.
I have been using it for a couple of weeks not and I can say that I am more than satisfied by the improvements made. Of course, it is very similar to Vista as we could all call it an upgrade to Vista. There are a lot of improvements though. I find Windows 7 to run a lot faster than what I experienced on Vista (especially on old hardware).
One of the black points of W7 for the moment has been a bug with the legacy Transport Driver Interface causing BSOD when accessing windows shares (Samba Shares / SMB Shares… whatever rocks your boat). The error message being “IRQL_NOT_LESS_OR_EQUAL tdx!TdxEventReceiveConnection.” and complaining about tdx.sys.
Many people found out that it would sometimes be caused by conflicts between network card drivers and Anti-virus programs and tdx.sys.
All the fixes given on the web could sometimes prevent those BSOD but yesterday, Microsoft released a fix on their website and so far… it seems to have fixed the problem.
You can find the hotfix here: KB967891
It is also said that the build 7032 fixed this issue. It is not a public release so I cannot access it sadly
