Mr Key Shop: Windows, Office and antivirus licences by email

Shopping at Mr Key Shop? See all current Mr Key Shop discount codes and deals, checked regularly.

Mr Key Shop sells software licences delivered by email: Windows and Office product keys, Microsoft 365 subscriptions, antivirus and VPN plans, server software, CAD tools and handy utilities. It is run by UK Soft Ltd, a company registered in London in 2020, and offers free set-up support in English and Italian. Prices can be shown in pounds, euros or dollars.

It helps to know where the keys come from. Mr Key Shop's About page says it buys unused Microsoft licences from businesses that have switched to cloud or subscription services, and resells them. It relies on a 2012 EU court ruling on second-hand software, and on later German rulings that also cover licences split from volume agreements. Its product pages describe the keys as genuine, and some bundles as retail licences. So much of the Microsoft range appears to be pre-owned rather than sold new by Microsoft, and we could not check the origin of individual keys. If you need licences for a business that may be audited, ask the shop for documentation before buying.

The site blocks automated visits, so we used archived copies of its own pages. Prices below are as they appeared there.

What's worth a look

• Windows 11 Home: listed at €49.99 when we checked an archived copy of its site (March 2026), with an official download link and activation instructions.
• Office 2024 Home for Mac or PC: a one-off licence for Word, Excel and PowerPoint on one device, listed at €139 when we checked an archived copy (September 2026).
• Microsoft 365 Personal (1 year): activated straight onto your email address rather than with a key, listed at €41.99 in the same September 2026 snapshot.

Current offers

We don't have any Mr Key Shop codes listed right now. On its own site you will find:

• Deal of the Day: each menu category features a rotating discounted product.
• Bundles: Windows paired with Office, antivirus or PDF software, grouped for families, students, remote workers and small businesses.

How to save more

• Switch the currency to GBP before checkout so you see the price in pounds and avoid card conversion fees.
• Check compatibility first. Refunds and replacements are only available within 14 days, and not once a key has been activated, so make sure you have the right edition for your device.
• Compare a bundle with buying each licence on its own, especially if you need Windows and Office for a new PC.
