They'd be more than willing to help you to get your software back.
if they still exist in the Windows.OLD
Well, don't count on it....
I reinstalled Vista a couple of months ago and found that the "Windows.OLD" folder does contain most of the old files, BUT.....
Some of the system files/folders in this folder are 'linked' with the new installation.
I found that out when I started cleaning out alot of files from the "Windows.OLD" folder..... Visat didn't like that

Plus I lost 1½ years of stored emails...... I had hoped that I could restore the .pst that Outlook automatically uses for storing whatever is my inbox/sent mails/etc etc from that folder.
Sadly though.... The new installation of Outlook had overwritten the file in the "Windows.OLD" folder...
Clever move, Microsoft.... (not)
