I was checking out the collating sequence on Windows 7 for a friend and found this post on SevenForums:

Numerical Sorting in Windows Explorer - Enable or Disable - Windows 7 Help Forums

Curious, I decided to give it a go on W10 even though this computer did not have the full key in the registry. I was not especially brave since I had saved a full image this morning. (You do have to reboot between changes for them to take effect.)

I created 8 files numbered 01, 1, 02, 2, 4, 15, 25, and 45. Then I downloaded the .reg files from that web site and applied them to see what happens. It appears W10 changed the default. It also appears the changes are still valid choices.

Anyway, W10 default is definitely with numeric sort enabled. As I created them, they came out in 01, 1, 02, 2, 4, 15, 25, and 45. (I don't know if the leading 0 is disregarded completely and might sort differently at some times, but they are in true numeric sequence since lead 0s should be disregarded.)

I ran the one to enable them first since disabled was the W7 default, and nothing changed. That reinforced that the defaults have been switched.

Then I ran the one to disable the numeric sort and the sequence changed to 01, 02, 1, 15, 2, 25, 4, 45. Basically straight ASCII collating sequence, not the numeric sequence Windows provides.

Anyway, I thought someone might be interested, and perhaps the equivalent information could be added to the Tutorials for W10 (reversing the default spec).
