Note: I am in the painful process of moving software to a new Win7 machine. Win7 has crashed once a day for 3 days now. On a positive note, Win7 finally recognized 5 new pieces of hardware today and installed drivers for them (keyboard, mouse, etc). The Win7 system can't seem to access sites hosted on github, sourceforge, gitorious, etc. I miss old WinXP! I will probably miss some updates during this transition period.
