Yes, though you do not need to reload Windows 10 (and unless you have verified install media, probably cannot at this point). If you want to completely wipe the drive first, there are utilities for doing just that -- some free, some commercial.  A clean install does not necessarily wipe the drive completely.    
Hi everyone, I plan on selling my Vostro 3591 so I will need to factory reset it. However, I purchased it in 2020 so the factory image shipped with Windows 10. I'm currently running Windows 11 and the latest build of this model also ships with Windows 11 Pro. So I was wondering if there was a way to get an updated factory image with Windows 11? On a side note, does Dell AU purchase used laptops that were purchased directly from Dell?
