MacBook Pro drive compression killed my login

Yesterday morning I got the bright idea, since I had so many problems running out of space, to compress the drive and the underlying folders. The process said it would take about 6 hours but was complete in under an hour. Anxious to reboot and see just how much more room I had, I did so very quickly and found that my login on the Windows side (Bootcamp) failed several times and found no way to fix it. I did see one site that mentioned doing an alteration of the registry but I can't find a way to access it. Because I can't get into Bootcamp, I can't find a way to see which version is installed. Attached is the error I repeatedly encountered. Thank you in advance for any feedback you can provide!

Hello,
Try strelec livecd in uefi mode.
If boot is successful create new user and browse for old user account and copy data.

I downloaded Strelec but when I try to run any of the exe files it asks for a password.
