A few years ago I upgraded from Win 7 to Win 10. The was the free upgrade for Windows 7 users. The upgrade was done on top of my Windows 7 installation as opposed to doing a clean Windows 10 install.
Prior to the upgrade I had a folder on my desktop which Windows evidently encrypted (without my intervention) as indicated by green text file/folder names. I've read that Windows will do this if the files originated from a Mac (which they originally did). Anyway after the upgrade to Windows 10, the folder disappeared from my desktop. Unfortunately I had been using this folder as my working folder so it ended up containing about 30 new files that I created, which was source code I wrote. I am wondering if it is possible for me to recover this missing folder.
My understanding is that Windows 7 uses a different set of encryption keys than Windows 10. I think that during the upgrade I was asked to back up my keys (certificate). I do have single .pfx file I saved off to another drive which might contain the file key / certificate.
IF this .pfx file is a backup Windows 7 certificate can I import it into Windows 10 allow me access my encrypted files? I'm really unclear what the needed steps are and which category of certificate this falls under (Personal Certificates?) Please provide any explanations about what I need to do and possibly any suggestions/steps to make the file recovery happen.
A few notes about my system:
- A Windows 7 restore isn't possible since I had it disabled at the time.
- My Windows.old folder was automatically deleted by Windows 10 days after the upgrade so it is no longer available.
- I am the only one using this computer and only have 1 account.
- My Windows username and password haven't changed.
- My boot SSD drive and mobo are still the same as before the upgrade.
I'd really appreciate your help in guiding me to recover my semester's worth of work.
