I'm not a complete noob to the slic method and have done Vista since release... by looking at the site I see that Win7 won't be much different and I shouldn't have any problems. There's one thing I'm wondering though and it's the Win7 "Virtual WinXP Mode". Assuming Win7 is slic'd and working... do we know anything about ensuring the WinXP mode can be registered and working as well? From what I've see WinXP mode requires a "new" key that allows it to work under the Win7 OS. Is this true? or will my old retail key for WinXP SP3 still work for "registering" WinXP mode? Thanks for any info.
