The first laptopshop I looked at, had 2 laptops (both HP) that met your first three requirements (Windows 7 already installed), but they were 1100 euro. Most Windows 7 laptops now are business class laptops, and those are more expensive than the price you need.
That indeed leaves downgrading as a cheaper option. But whatever is published in specifications, it never is the downgradability to Windows 7. So I think you'll need personal advice from a shop or the sales department of the maker.
Two questions since you didn't tell WHY you need Windows 7?
- Would a Windows 10 laptop with Windows 7 running in a virtual machine be acceptable?
- How about Windows 10 disguised as Windows 7 by installing Classic Shell. That's what I run here. Looks quite good and I have the weather app and better safety as a bonus.
Hi.
I am planning to buy a new laptop, but I have specific requirements:
- screen must be 17''
- I must be able to install Windows 7 64 bit on it and have all the drivers work properly
- 8 or more ram
- price: 500 GBP/600 EUR
- brand is irrelevant as long as I can have all requirements given.
Please, don't send me to Google. It's filled up with gazillions of computers but I need an opinion of real people here.
