Dude you have more problems than seem possible.. I have 8 different systems running windows, not counting all of the countless VMs that use for testing, etc. And I don't recall the last system crash that required a reinstall. Last issue was my daughterinlaws laptop, that had to be 4 years old at least died. They bought a new one - something with the fan or the thermal paste, it would only stay on for a few minutes. She had all her stuff backed up that she needed, but I pull the drive and could of pulled any info she needed off of it. She just wanted to wipe it before she trashed the thing.
Why don't you just take a full image as your backup if your having to reinstall the system?
As to your question at hand - just export it. Built in functionality, no need for any addon or 3rd party tool
