Upgrading rom is necessary re-install all programs again?

[napolibit]

As told in object, when i'm upgrading the Tytn rom (the same family rom) how can i install all the programs by backup file?
Or have i to install them from the beginning?

The hard and fast answer is imagine reinstalling windows on your pc... Would you have to reinstall all the programs? So, the answer is yes. However, you can try Settings Savior, a program created by a member of this forum that will automatically reinstall programs for you as well as resets your settings... check out the post http://forum.xda-developers.com/showthread.php?t=308100&highlight=settings+saviour to see what I'm talking about.

YES, if you will have to. Best is to back up your data. Save you some effort

But, if i make a backup file of programs installed and i'm upgrading my tytn from a rom version to another rom version of the same kind (Schap's 3.57a to 3.57b, for example) when i'll upload the backup file are there difference on register key of windows system.
I'm asking for knowing if the programs can running without problems about difference of register key from old rom version to new.

no.

you must reinstall as the registry keys needed will not be there.

use settingsaviour as the first reply said and it makes it very quick though.
