In terms of the backup and recovery, I would personally strongly recommend using Macrium Reflect (more on this below) instead of any Microsoft or built-in solution.

If you do that, you can restore your PC from the saved image and don't have to worry about license issues.

If you're asking how much space the Windows system files take, then no, there is no way to determine that.  You can see how much space is USED in your OS partition using File Manager and simply selecting Options for the drive.

The size of 23GB sounds typical for usage of a Win10 PC, and if you were to use Macrium Reflect to back that up, it would take about HALF that space on a USB stick or external drive.

You don't need to redo the recovery disks, in fact, using the HP utility, you can't -- as it only allows you to do that once.  But understand, those only recover the OS and the drivers.  They do not recover any apps you installed, your personal data, or any of your settings.

-----------------------------------

I personally prefer to use third-party Backup solutions as they tend to be both more flexible and more reliable than any built-in solutions.

Macrium Reflect (MR) provides a FREE version that can be used to image and restore partitions or entire drives.

What I recommend is the following:
1) Download and install Macrium Reflect (MR) from here: http://www.macrium.com/reflectfree.aspx
2) Run MR and choose the option: "Create an image of the partition(s) required to backup and restore Windows" to write a full backup to an external drive or USB stick
3) Use the option to create a boot USB stick or CD

My experience is that MR, when using the High Compression option, typically can compress the saved image file to about 50% of the USED space in the OS partition. This means if you have an 80GB OS partition, and 40GB is used, MR only needs about 20GB to store the image file.

I use this all the time and it typically takes less than 15 minutes to do the image backup and about the same time or less to do a restore.

Plus, MR has the option to Add a Recovery Boot Menu entry. This allows you then to boot into WinRE, and you can then use that to do a restore -- when you can't boot into Windows!

NOW, you have the means to restore a full working system from the external drive or USB stick in only a few minutes.
