Is dramatic drop (>30%) in space usage normal?

Hello - wasn't sure if this belongs in Performance or Upgrades ...

I‘ve recently completed the Win7 –> Win10 migration and was quite surprised to find that space usage on my OS-Apps drive – after deleting windows.old – had dropped by ≈ 30% (38% adjusting for the hibernation file (which has now been disabled)):




All of my Apps (haven’t tested games yet) are still available and functional albeit with help from Compatibility mode. Potential causes I can think of:

1. There’s a bunch of Win7 functionality missing that I’ve not yet run into
2. Win10 has an amazingly smaller footprint for equivalent functionality (which would be even more amazing given the number of running processes and services vs. Win7)
3. I’ve done something wrong
4. Something else outside of my “circle of knowledge”

Should I be concerned?

Thanx in advance for your time and expertise.
