A Genuine Retail License, Not An OEM Key Tied To One Machine

Many discounted Windows keys are OEM licenses, which are permanently tied to the original device they were activated on and can't be transferred. Mr Key Shop's Windows 11 Pro key is specifically sold as a genuine Retail license — a perpetual license type that isn't locked to a single piece of hardware the way OEM keys are.

A genuine Retail license, not OEM

The product is specifically sold as a genuine, perpetual Retail license rather than an OEM key — a concrete licensing distinction, since Retail licenses can be transferred to a new device, unlike OEM keys tied permanently to original hardware.

A documented 4.8/5 rating across 113 reviews

The product carries a specific, aggregated rating of 4.8 out of 5 stars from 113 reviews — a concrete, counted customer feedback figure rather than an unquantified "highly rated" claim.

A clear feature comparison against Windows Home

Pro specifically adds BitLocker drive encryption, Remote Desktop as a host, Hyper-V virtualization, Group Policy management, and domain join — named, itemized features absent from the Home edition, rather than a vague "more features" claim.

Support for up to 2TB of RAM

Windows 11 Pro specifically supports up to 2TB of RAM, compared to 128GB on the Home edition — a documented, measurable hardware ceiling difference relevant to users running memory-intensive workloads.

Instant digital delivery

The product key is delivered by email within minutes of purchase — a specific, documented delivery method rather than requiring physical shipping or an extended waiting period.

A free upgrade path from Windows 11 Home

Customers who previously purchased Windows 11 Home can upgrade to Pro simply by entering the new product key under Settings > System > Activation, with Pro features unlocking automatically within minutes — a concrete, documented upgrade process rather than requiring a full reinstall.

Free dedicated technical support included

The purchase includes free technical support to help with activation or installation issues — a concrete, included service rather than a bare product key with no backup assistance.
