How to associate a PFX certificate from different identity (Windows-7) to upgraded computer (Windows-10) with new identity?
User upgraded to Windows-10 from Windows-7 created logon user identities are different from original. Encrypted data files were copied to new computer, but unable to access/open encrypted files. Installed .PFX and .CER objects from old PC to new one using certlm.msc. Still no joy! Assume the issue is different identities. Old identity is XXX-SSD while new identity is MySSD. CER and PFX objects installed from flash drive.
Reviewing CertLM the certificates appear in following:
CERTIFICATE - Issued To [Comments]
Personal - MySSD [new identity]
Trusted Root Certification XXX-SSD [prior identity]
Intermediate Certification Authorities XXX-SSD [prior identity]
Trusted People MySSD [new identity]
Other People MySSD [new identity]
Homegroup Machine Certificates - XXX-SURFACE
XXX-SSD-PC
How do I associate the prior PFX with identity XXX-SSD to new identity MySSD?

In short, you can't. A certificate, once installed, is unique to the SID of the computer and its OS. A new certificate must be installed.

For my own clarification. I have imported .pfx object from one OS upgrade to another before and had no difficulty with encryption. With the enhanced security of Windows-10 versus upgrade from Windows-7 I moved the Win-10 OS from HDD drive to SSD drive - The end result is I can no longer boot into the Win-7 OS to un-encrypt the files in that environment. To make matters worse, I changed the logon identity as defined in initial question. Microsoft did not provide an adequate solution for those who wanted to install the new Win-10 OS on an SSD drive during the upgrade. Is there a way of recovering the win-7 boot to enable me to return to that OS to un-encrypt the files?

Thanks for your comments - I now have a better understanding of the way I box myself in. Any suggestions on How to get a Dual Boot option which would enable me to boot into the Win-7 OS?
To be honest, I haven't yet tried to dual boot Windows 10 with any other OS. I am still trying to get past some of the worms that I have found. You might want to try setting up the dual boot on the Windows 7 drive and then point the secondary boot to Windows 10 on the SSD drive, but this is only speculation on my part.
