How long does it take to reset a laptop or desktop? The time to reset a PC depends on the data stored on the PC, the more data stored on it, the more time resetting a PC will cost.

I have been backing up the important files, and removing what I need, how long does it take to factory reset a PC? Any tips to make factory reset as fast as possible (without rushing and messing up?) I have had my HP Windows 10 PC for about 3 years, no heavy adobe software but has a few Microsoft Office, a few art apps, about 8 photos folders over 4 - 20 photos, iTunes library of about 400 songs, most of these audio files are on my computer, and of course 3 years of words documents.
