Apologies if I’m in “Captain Obvious” territory, but isn’t Microsoft’s own Windows OS installer what created (and sized) the original recovery partitions for probably 99.9% of Windows 10 installations?

Great quality control there Microsoft! Have you and Boeing hanging out?

Yep. And my system was a clean install on a new 2TB drive just a few weeks ago. I gave the Win 10 installer all 2TB to do whatever it wanted.

It chose to create a 100MB EFI partition at the front, and a 522MB recovery partition at the end. Everything in the middle was handed to the Windows C:\ drive.

I subsequently shrunk the C:\ drive to create 400GB of over-provisioning for this SSD.
