Email addresses in my system/files backup?

Two weeks ago I lost a C:| drive and a repairer replaced it with Win 10 and some key software but not MS Home. I have used MS Home for years and have access to Sys and File backups for the last few months, mix of full and incremental, on an ext drive but cannot find specific items (e.g. Thunderbird address book would be precious) in them using File Explorer…
My tech background is 55yrs obsolete but I can study if selective recovery is written up anywhere.
I am reinstalling MS Home, but unsure how to avoid damage to years of existing archives.

Can someone guide me to a source of help, please?


Normally,questions about Windows are not entertained on this forum,
but since it also involves the MSH archive, it became a mixed question…

I’m sorry that you fell into the wrong hands.
Just typical of unscrupulous pc repair people…

I know, the change to Win 10 is disputable, because of the fact that Ms is dropping support for
older OS versions.

The crux of your situation is which backup program you used - 1 program or more?
Did you backup MSH with its internal backup facility?

Some Help links -take your time to read and understand…

MailStore Staff , advises to delete the new archive in your Documents in Win 10
and that maybe the better option from what I wrote months ago.
Just replace it with the “old” archive from your previous system backup.
In the backup you’ll have to find that folder under your My Documents.
Restore it to your Documents in Win 10

As for the Thunderbird contacts:

I have no way of knowing if you backed up your TB profile folders or
what you backed up and in what way…

I understand that you are somewhat technically challenged, but you can’t - or shouldn’t-
continue that way without incrementally learning some things that are helpful in managing your computer…
I hope that the repair facility put in Classic menu or similar to get used to Win 10.
It helps with the transition.

You may have to re-install the backup program if other than the native Windows backup.
