Windows 7 RC build 7100 is here now.
There is a new Aero Theme named Architecture as well and you can have the desktop background change automatically like a slideshow if you want to.
I have used it since it was made available for MSDN members last week and is happy with it for the most part.
One thing I don’t like is when you quickly use Alt+Tab several times there is too much flicker on the screen because each application you switch between shows up.
Together with Office 2007 SP 2 I’m really happy with the result and an it is much snappier than Windows Vista. I also run AutoCAD 2010, AutoCAD Architectural 2010, Visual Studio 2008, SQL Server 2008, Mozy, Carbonite and more on this laptop. It is a very basic laptop with low hardware specs but with Windows 7 installed it works great for what I use it for.
I tried the beta of F-secure’s antivirus product that is in beta for Windows 7 but had to uninstall it because it hanged Windows from time to time quite badly.
I will use Windows 7 RC as my default OS even for production usage now.
