What is ShowKeyPlus?
ShowKeyPlus displays Windows product-key information in a desktop interface. Use it to inspect an installed or firmware-stored key, check the Windows edition associated with a key you already have, or retrieve key information from a backed-up Windows installation. It can also save the displayed information for later reference.
Key recovery is not the same as finding a unique activation key for every PC. The publisher explains that a free Windows 10 upgrade can use a digital entitlement, in which case the displayed key is generic. Backup recovery requires a backup containing a Windows folder.
The linked download is the publisher’s Windows x64 ZIP package for version 1.1.18.0, not the separate x86 package or Microsoft Store edition. Its release notes add an updated Windows 11-style interface and Office 2010–2021 key checking. A Windows 11-style interface is not, by itself, a compatibility guarantee.
