I’ve installed the Windows 7 Release Candidate on all my machines. It’s running on a custom-built Intel Core 2 Duo desktop, a HP Mini 1000 Netbook, and a 15 inch Macbook Pro running Boot Camp. They are all running very well. The only “problem” is I can’t get the microphone in the HP Mini 1000 to work but I haven’t spent time trying to fix that yet. The other machines are running great and the only times I have needed to reboot have been when Windows Update sent some test patches through the system.
Best of all, sleep mode finally WORKS! On my Macbook Pro it was > 70% chance that if I closed the lid or otherwise put the machine to sleep, it would hang and need to be powered off without the proper shutdown procedure. Now I snap the lid shut and it goes to sleep like a little baby that has drunk Nyquil.
Anyway, a great personalization feature of Windows 7 is themes. There are some included by default that are beautiful. Architecture, Characters, and Scenes are the ones I like the most.
This entry from the “Engineering Windows 7 Blog” explains how to create, save, and share Windows 7 themes.
