The only way to "turn Hyper-V off" is to uninstall the role. Which I wouldn't recommend for any reason unless you plan on removing it permanently.

More importantly, I don't understand what you are trying to do. Your topic subject line talks about doing a backup. Which that process doesn't really do. And in the description, you talk about doing "a very quick install" of Hyper-V....which makes no sense given the process you laid out.

So what are you trying to accomplish here?!?

I am trying to install some software (i.e. Microsoft Office, etc) on one of my existing HyperV VMs but want to make a quick backup of my exiting HyperV VM first.

In the above I am basically turning one of the VMs off, doing the steps, etc.

Do you have any other BETTER steps ?

Snapshot it and if all goes well delete the snapshot.

Snapshots allow you to revert to a previous point in time.  
This is something I do in my VM environment when I plan to make some sort of modification.

Note: the deleting of the snapshot can take some time so wait until you see it completed within in Hyper-V Console.

You really backup you servers regularly as best practice VM or Physical.

Exporting a VM vs copying all of its files takes the same amount of time. I don't what yoi'e heard that makes not want to "take the time to EXPORT/etc.". That is the best "quick" solution. Note that snapshots are not supported in production.

Note that snapshots are not supported in production. Cliff can you cite some sources other than anecdotal evidence.

I would snapshot (check mark) roll back on failure, if success, delete checkmark and let it merge

How about from someone on the team and that there is a feature in server 2016 called "production checkpoints. A bit more than anecdotal.

Yes! it can be done with two ways:

1. Power off that VM and copy its VHD/VHDX to another location.
if any thing went wrong during testing just point HDD location to the VHD/VHDX you copied.

2.(Easiest way) Make Snapshot. it stores your VM state from which you can easily call your VM back if any thing went wrong in testing.
