Back to blank? If Windows did any decent housekeeping it would go back to blank.. It probably stays there, abandoned, and will get updated again if you return to roaming. Take 5 minutes and find out. Make restore point, go back to local, check.
once i change to roaming that profile path will be the central profile value as u said.
But if i again switch it back to local user from my computer\ properties\ advanced\ user profole to local will the central profile value change back to blank???
or it will maintain same profile path and acts as local user???
is the behaviour different in win 7 or vista other than the .v2 extension??
Here is not a smart-alec answer, just the way it is with me:
Vista: Don't know, don't care.
Win 7: Don't know, don't care. (until I buy a Cray CX1-iWS)
Microsoft has good write-ups on this subject concerning profiles involving XP Vista and Win 7 in various scenarios.
