Before an old Windows XP installation was removed all the files from Windows partition were backed up. A new Windows XP installation was then set up at the same partition. The certificate which is used in Internet Explorer was not exported. Now we wish to obtain that certificate from backup files.
The certificate itself was actually recovered, but is not useful, because its private key could not be recovered. Is there a way to also recover private key from backup files?
The certificate was recovered by copying files from
Documents and Settings\<username>\ApplicationData\Microsoft\SystemCertificates\My\Certificates to the new Windows installation.
We also tried copying all the backed up files to another partition and booting from it. However the boot process never ends, it gets stuck.
