Which of these software use Windows registry?

I store my data on a separate partition which allows me to regularly restore my windows system partition to an earlier state without having to worry about losing any data.

Of course, I have to re-install/re-configure anything that I had done since the creation of that system partition version I've just restored.

It occurs to me that certain OS-agnostic software packages don't use the Windows registry, which to me means I could 'install' them on a non-system partition; this would save me from having to re-install them/update them after restoring a system partition image prior to me having installed/updated these packages.

I believe PHP and Apache to be such packages; wondering about MySQL.

Seems Composer and any packages I install using Composer qualify too.

Looking for confirmation of the packages before I start moving them off my system partition and reconfigure accordingly.

It seems to me you'd be much better off asking the manufacturer(s) this question.

Thanks for your thought.

Anyone else?
If you ask what does NOT use the Registry, you can count such packages on the fingers of one hand.

Almost ALL Windows Software uses the Registry.

If you or a user hoses the system so badly it has to be reinstalled, having software on another partition won't save much at all.

Installation paths will all be stored in registry no matter where it is.
Well, for software like Apache, PHP, and MySQL you could install Cygwin and then install those packages under than,.

Cygwin is a Linux like environment that runs on Windows.  When you install software under Cygwin it is like you installed it on Linux, so no Windows Registry entries.

Although Cygwin may update the Windows registry, there are no entries that it requires to be there to run.
Thanks - I tested PHP and Apache.

Works fine as portable apps (i.e. didn't use installers).  

The only 2 registries I'm using:
I added php to path and setup apache to run as a service

Thanks everyone for your help.

Good to hear that you managed to get PHP and Apache working this way.
You're welcome and thanks for the grade.
