Which Used Computer for Windows 11
John P - 28/8/25 at 04:02 PM

Just after a bit of advice.

I have an old Dell Optiplex 755 desktop which came from my daughter's architects company so had been upgraded and now also has a SSD which in installed around a year ago. It's running Windows 10 Home and really does everything I need but it can't be upgraded to Windows 11.

I was thinking about trying to source another used computer which was Windows 11 compliant. My SSD has a legal copy of Windows 10 so I'm hoping I could simply transfer this drive to the new PC and alter the BIOS if necessary and so that it runs my existing Windows 10. It looks like I could then update to Windows 11 for free.

Firstly, is it as easy as I'm hoping and secondly does anyone have any recommendations for a suitable brand and model of computer I should look out for, hopefully at a budget price.

I've been very pleased with the existing Dell but there are so many models advertised used on eBay etc. that I'm a bit confused.

John.

there are hacks for older computers to allow win11 install

it will take me a little while to find them, but perhaps others already have links for them.

edit, but why do you want win11?

It does depend on what version of windows 10 you have. I can't remember what they call them, but some allow hardware changes (and therefore moving to another pc) but some can't transfer away and are tied to the original pc.

To bypass the checks on your current pc, have a look into 'tpm bypass'. Its not difficult, just a few extra steps early on. As for computer hardware, plenty of places do refurbed machines that can accept windows 11 for around £100 (as an example budget)

I do echo gremlins question though, why move to 11? You've already done what i consider the best 'performance per pound' upgrade which is the move to solid state drives. Any further hardware upgrade won't be as noticeable, and win 11 will take its share aswell.

We are in a similar situation.

Recebtly my wifes lappy screen packed up, and we bought a Dell used laptop via ebay, apparently "refurbished". To be fair it is in very good condition, and was not expensive. So we plan to do the same with our desktop (it is in our home study, and is where we store important files etc plushave a separate SSD backup linked to it)

Our lappy came from https://www.ebay.co.uk/usr/fitaurawholesale

I recommend putting in as much 'RAM' (memory) as the machine can take.

Thanks for the comments.

The only reason I'm considering going to Windows 11 is because Microsoft are ceasing support and upgrades from 14th October.

Not really sure how critical this.

When my last desk top was dying I bought one via eBay from skytech-outlet it was good value and has been fine.
