Thanks
Gabriel for your response - despite using Windows PCs since the mid-1980s, for home use I have typically bought a new computer(s) w/ a new OS and have simply reinstalled updated software and transferred files saved on external media (of course, external HDs or BIG USB flash drives currently).
I've never cloned a Windows HD for transfer so would be interested in others' opinions who may have tried this w/ iTunes and their success (or failure) story?
Yes there are a variety of 'migration' options & tools available when updating or upgrading to a new Windows computer, esp. 'files & settings' transfer; I've not done that either - my IT people at work have usually handled my computer OS upgrades over the years, so I have no experience there either.
Now a problem w/ Windows (and possibly iTunes, I don't know at least yet) is that a Windows OS version 'knows' the machine it is on and transfer to a different or new machine will typically not work; so I'm also wondering if iTunes stores the 'specifics' about the computer it is on and will refuse to be transferred to a new computer - again, I'm not sure and am hoping someone who has gone through this process will 'chime in' - thanks again for your quick response - this is always a sticky issue - Dave
