Over and above my previous IO categorisation of Windows 7 features, RC brings some welcome new additions and some hidden gems. An an example/rambling of some of my experiential Window 7 RC changes below.
Boot Time: My boot time is even quicker than the beta. Similar too is the time to login.
Internet Explorer 8: New tabs and in-private from right click on internet explorer icons
User Interface: Some general sensibility on dialogues. Take this one when importing pictures from camera; there are now snapshots of content
Networking: Home groups are now a little bit more intuitive (and consistent)
Migration & Backup: Backup/Restore/Easy Transfer and Imaging are simply outstanding. I might even reduce my use of SyncToy
Sounds: Bit softer. Device images – a few more.
Devices: USB/Bluetooth enumeration – Issues in Beta now fixed!
Themes: RC has some nice geographic specific background images (e.g. Sydney Harbour)
Windows Media Center: Faster, music collage and better menu responsiveness and options
In Australia using an EPG was mandatory for Media Center. Now with WIndows 7 Media Center you can use the EIT / broadcast EPG instead for DVB-T. Once it is running for a while (depends on whether a tuner is spare) - the EPG will populate itself with all the EIT data instead!!
Which is great too as it makes better use of my digital now TinyTwin dual USB tuner.
Application Compatibility: Windows 7 XP Mode
Boot Options: Windows 7 has yet another new feature in boot from VHD. Essentially it makes it easier than ever to set up multi-boot scenarios on a single machine.
Jeff Alexander has some great posts on 7 in general. This one on USB booting is very handy
Security: Biometric device integration with platform – very straight forward
