Hello,
got the official version of Windows 7 Professional 64 bit yesterday.

I guess a lot of people want to switch to Windows 7 and/or a 64 bit operating system, so here are my first impressions:

• during installation of Windows 7 you can now load drivers for your RAID drives from other devices (CD/DVD/USB). Finally no diskette drive needed anymore. Welcome to 2009, Microsoft.

• it's stable. I installed all my programs and had no crash so far, no matter if it's a native 64 bit version or a 32 bit version. Even the 'usual suspects' [tm] behave fine.

• it's fast and responsive

• the Vue 7.51 64 bit version renders definitely faster than the 32 bit version, even with scenes where memory (I upgraded from 4GB to 8GB) is NOT an issue. This is especially nice for the small preview render.

• remember to start it with administrative rights when you enter the serial number, if not you can type it again during the next start. Aaargh...

• the Nvidia driver for my GTX275 graphics card runs smoothly with Vue. There's one scene where for whatever reasons the textures won't show up in the navigation views. All my other scenes work fine. Maybe I forgot the set an option after the new Vue installation.

• like Windows Vista it has (compared to Windows XP) about one zillion unnecessary background services running. Should run even faster when I remove the ones I don't need.

• 8GB RAM rulez.

If you have any questions feel free to ask.
