In that case, I suppose that I will be stuck Windows 10?
By ignoring 'Home and small business" option on the Dell website I went to the next one up, just "Business", possibly, and there, by speaking to the sales staff, I was able to insist on W7, they send the machine loaded with W7 and the disc for an optional upgrade to W10. Also plenty of quality, refurbished ex lease machines out there that will have W7 on them, not all the business world took kindly to W10!
