If I sell my Windows laptop (to buy a used Mini M2 Pro) is it easy to wipe and reinstall Windows?

[Jerry®]

I really want an Apple Silicon Mac that I could use as my main computer and because I really do not like Windows. A seller is selling a Mac Mini M2 PRO 16/512 for $350. I have an Acer Nitro V “gaming” laptop that has similar specs except I don’t know how to equate the intel processor it has (i7-7700HQ)with an M2 PRO mini. My Acer has 16GB DDR4 RAM, 512 SSD (PCIe SSD) and came with Windows 10 Home when I bought it. But the guy I bought it from didn’t nuke and pave it - long story - so, in order to get it ready to sell I’d of course want to totally wipe it and reinstall Windows but I have no idea how to do that. Can Windows 10 be reinstalled via the internet? Does it need some sort of license key #?

From a quick search on eBay looks like I could get around $350-400 for it. I have the original box and dIdd just need to wipe it and clean it up a bit.

Any advice on selling it? Getting it ready to sell? Wiping it, etc?
