Portable ProduKey

This is the portable edition of ProduKey, a tiny software utility whose sole purpose is to display the CD keys of Microsoft Office and Windows-related products from your computer. It is very simple to work with it, even if you have limited experience with software programs.
As installation is not a prerequisite, you can simply drop the executable file anywhere on the hard disk and it directly. Alternatively, you can save ProduKey to a USB flash disk or similar storage unit, in order to run it on any computer with minimum effort.
What's important to take into consideration is that the Windows Registry area does not get entry updates or leave files behind on the hard disk after removal.
The interface of the application is made from a standard window with a plain and simple layout, where the serial numbers in question are automatically shown at startup. Details include the product name and ID.
You can copy one or more selected items to the Clipboard, the product key or ID, generate an HTML report, automatically resize the columns, as well as refresh the list.
An important feature of ProduKey is that it gives you the possibility of switching the source from your local computer to external Windows installers from all disks which are currently plugged into the computer, to an external Windows directory or Software Registry key, to a remote computer, and others.
In addition, you can mark even and odd rows to tell items apart more easily, add a header line to a CSV or tab-delimited file, as well as save the selected or all items to TXT, XML or CSV, aside from HTML.
ProduKey is very low-demanding when it comes to the CPU and RAM, thus it doesn't interrupt user activity. No errors were shown in our evaluation, and the tool did not hang or crash. In conclusion, ProduKey packs surprising features for finding out the lost or forgotten serial numbers to Microsoft-related products.
