IsiWinKey - Version 1.0 This software is intended for people who has lost his MS Windows 95/98 registration numbers and want to have it safe in case they need to reinstall Windows. If you haven't had the need yet, at same point you'll need to. Windows will ask for the registration numbers every time you install or reinstall MS Windows in any computer. The original registration numbers come printed in a piece of paper and if it gets wet or incinerated or lost you got a problem. Registration numbers are not all the same in every Windows installation disk and other people’s registration numbers, usually won’t work with your Windows disk.. This program solves that problem but you must run it while windows is still working.
