MSKeyViewer Plus

MSKeyViewer Plus is a small and portable utility that displays the installation keys, service pack levels, product IDs and versions of your installed applications. It also supports non-licensed programs.
Since installation is not a prerequisite, you can drop the executable file anywhere on the hard drive and run it directly.
Alternatively, you can move MSKeyViewer Plus to a USB flash drive or other similar storage unit, and run it on any computer to view application data.
What's more important is that no items remain on the hard drive or in the Windows Registry after program removal.
The interface of the application is based on a modern window with a well-organized layout. The WYSIWYG concept definitely applies to MSKeyViewer Plus, since there are no other options available, besides the ones shown in main frame.
The tool automatically detects all applications installed on your workstation. Therefore, you can view the product key, service pack level and product ID of Windows or Microsoft Office, together with the versions of non-licensed products. The selected or entire data can be copied to the Clipboard for further evaluation.
MSKeyViewer Plus uses a barely noticeable amount of CPU and system memory, so it does not interfere with the runtime of other running apps. It has a good response time and works smoothly. We haven't encountered any difficulties in our testing, as the app did not hang, crash or notify us of any errors. Thanks to its intuitive layout and overall simplicity, first-time users can effortlessly work with MSKeyViewer Plus.
