ShowKeyPlus for Windows

Quick summary of ShowKeyPlus

ShowKeyPlus, from Superfly Inc., is a lightweight utility that retrieves the Windows product key used on a PC. It’s aimed at users who prefer a graphical helper rather than running command-line queries, and it adds features that many similar tools do not, such as verification and export options. The app is available at no cost and is distributed as open-source software.

Portable, no-install convenience

• Runs without a traditional installation — just download and launch the executable.
• Ideal for carrying on a USB stick so you can check product keys on multiple machines.
• A straightforward, minimal interface reveals the detected key automatically when the program examines your system.
• Includes a toggle to conceal the product key on-screen to prevent casual viewing by others.

Backup, display, and export options

• Can scan a Windows backup (point the tool to the folder) and extract product keys if the backup contains a Windows directory.
• Shows information about the previous operating system when the machine has been upgraded, helping you track past installs.
• Lets you save discovered information for later reference; note that exported results are written in plain TXT format.
• Offers a verification feature so you can confirm keys rather than merely viewing them.

Who benefits from using it

ShowKeyPlus is suitable for a wide range of people — from IT professionals who need a quick lookup tool to everyday users who aren’t comfortable using PowerShell or registry commands. Its simple workflow and portability make it especially useful when working across multiple devices or when reinstalling Windows.

How it compares and alternatives

• A viable alternative to NirSoft’s ProduKey for users seeking an open-source option with portability and verification features.
• Stands out for its ability to verify and save keys, capabilities not commonly bundled together in many competing utilities.
