How to factory reset Lenovo Thinkcentre M720q when password not known?

[itm]

I'm trying to reset Windows 10 on a Lenovo Thinkcentre M720q, but I don't have the user password. Does anyone know how/if it's possible?
If not, is my best bet to get a fresh Windows 10 ISO and wipe it/start again?

Just wipe the drive and install the latest version of windows. It'll be near as fast as faffing about to reset admin password.
Sounds like you'd want to reinstall anyway, rather than use another person/company's OS install.

Where did you get the machine from?

Yes I'm beginning to think that's the only solution. I just wanted to avoid the hassle of having to find the right drivers for the chipset/audio/etc after Windows was installed (the Lenovo website lists alternative options for some of the hardware, so there will probably be some trial and error involved).
It's a corporate desktop from a company that went under last year.

Hopefully you're right. I'm just never confident that there won't be some funky piece of proprietary hardware that the standard Windows update doesn't properly handle. At the very least I'd expect to have to install chipset drivers manually, based on past experience.
