I rolled back to WP8.1 so I could have the latest build (10572) and after updating to that build I performed a hard reset to make a clean start, and my apps won't restore. The show up on the start screen, but greyed out, not showing on the app list neither on the store donwload section. Do I need to go back to 8.1, restore backup and then update to 10 (10572)? I want a fresh start from 10 =/

I had a similar problem, the greyed apps were stored on sd-card. Check that out.

I had to format sd, and reinstall all of them

(sorry for the bad english! argentine dude here)

They were installed on the internal storage, but they were supposedly backed up on the cloud, and the restore seems to work but the apps won't download...
No worry, you have a good english, I'm from Venezuela myself so you know ;)
